Article VI - Field Events
Comment: Field events is a general term used to
classify individual disc sport events, namely: accuracy,
distance, maximum time aloft (hereinafter referred to as
"MTA"), throw, run and catch (hereinafter referred to
as "TRC"), and self-caught flight (hereinafter referred
to as "SCF"). The common link among the field events is
the competitive measurement of a particular basic skill. Accuracy
measures a player's ability to consistently throw a disc through
a specified target. Distance measures how far a player can throw
a disc. MTA measures the length of time a player's throw is in
the air. TRC measures the distance a player can throw a disc and
catch the throw, prior to the throw hitting the ground, and SCF
combines the events of MTA and TRC.

601 Field of Play
- 601.01 General: The
playing field for field events may have any
surface, although well-trimmed grass is
suggested, which is essentially level, free of
obstructions and/or holes, and affords reasonable
player safety.
- 601.02 Obstructions:
If there are permanent and predictable obstacles
which may affect the completion of a throw,
throwing sites should be located to minimize
potential problems. Once these obstructions have
been noted by the head or site judge, however, no
re-throw will be granted if the obstructions come
into play. Designated spectator areas shall be
considered an obstruction.
- 601.03 Accuracy: The
playing area in accuracy shall consist of seven
throwing stations, set at varying distances and
angles from the target; said stations being
clearly marked by foul lines which consist of a
front line and perpendicular sidelines, both of
which are 120 cm in length and between 5 cm and
10 cm in width. Small, flexible cones should be
used to mark the front corners. The location of
the throwing stations is determined by the target
itself and the lateral extension of its plane.
See Figures 6.1 and 6.2.

- A. Straight-Ahead Throwing Stations:
There are three straight-ahead throwing
stations, with respective distances of
13.5 m, 22.5 m, and 31.5 m from the
target. The midpoint of these stations
shall be on the imaginary line that makes
a perpendicular intersection of the
target plane at the midpoint of the
target.
- B. Left-Angle Stations: There are
two left-angle stations which are located
to the player's left of the target; one
station 13.5 m from the target and at an
angle to the target such that a line
drawn from the midpoint of the front foul
line of the station and intersecting the
target plane at a perpendicular angle
will be 4.5 m in length; and one station
located 22.5 m from the target along the
same angle as the 4.5 m line, such that a
line drawn from the midpoint of the front
foul line of the station and intersecting
the target plane at a perpendicular angle
shall be 7.5 m in length.
- C. Right-Angle Stations: There are
two right-angle stations which are
located to the player's right of the
target; one station 13.5 m from the
target and at an angle to the target such
that a line drawn from the midpoint of
the front foul line of the station and
intersecting the target plane at a
perpendicular angle will be 4.5 m in
length; and one station located 22.5 m
from the target along the same angle as
the 4.5 m line, such that a line drawn
from the midpoint of the front foul line
of the station and intersecting the
target plane at a perpendicular angle
shall be 7.5 m in length.
- D. Optional Field of Play: The
playing area may also use a moveable
target to create the correct angle
stations. Positioning for the target
should be painted on the ground. See
Figure 6.3.

Fig. 6.3
- 601.04 Distance: The playing area in distance
shall be of sufficient size to permit the entire course of the disc flights
to be contained within its perimeter, essentially level to insure an accurate
measurement, and in an area which permits an unblocked windflow. The layout
of the field shall be such that throws may be made with the prevailing
wind. There shall be five throwing sites, each marked with foul lines
which consist of a 3 m front line and perpendicular sidelines which are
3 m to 15 m in length. These lines shall be between 5 cm and 10 cm in
width. Small, flexible cones should be used to mark the front corners
of each site. At least 6 m of additional space shall be provided between
each throwing site. See Figure 6.4.
 Fig. 6.4
- 601.05 MTA: The field
for MTA shall be of sufficient size to permit the
entire course of the disc flights to be contained
within its perimeter, and essentially level. No
field markings or other delineations or
designations shall be required.
- 601.06 TRC: The field for TRC shall be of
sufficient size to permit the entire course of the disc flights to be
contained within its perimeter, andessentially level. Depending on the
field size and wind direction, one or more foul circles shall be clearly
marked by painted lines measuring 4 m in inside diameter. The lines shall
be between 5 cm and 10 cm in width. See Figure 6.5.
 Fig. 6.5
602 Equipment
- 602.01 Discs: A
player may use one or more of any type of flying
disc, so long as they meet the minimum
requirements set forth in Article I of the WFDF
rules and the specific requirements for accuracy
in paragraph 602.01(A). The
discs need not be identical.
- A. Special Restrictions: For game design and safety considerations,
discs in accuracy play must meet both the W.F.D.F. general disc specifications
(section 107) and these additional
specifications:
- (1) Rim configuration: must achieve a rim configuration rating
of 75 or greater (may not be beveled - see section 108 [D]).

electronic measuring devices with the ability to
measure throws to the cm up to 200 m in length,
shall be provided.
- 602.03 Stopwatches:
For MTA, four stopwatches with the ability to
measure time to one-hundredth of a second shall
be provided.
- 602.04 Field Target: In accuracy, a field
target shall be provided which shall consist of a two - dimensional structure,
made of non-flexible material, presenting a square target with 1.5 m sides,
the target area being set 1 m above the ground. The field target shall

 Fig. 6.6
603 Rules of Play
- 603.01 Accuracy:
- A. Play: A player shall make four
throws from each station for a total of
28 throws, with the objective to have as
many throws as possible pass through the
target area. He or she shall complete all
four throws at each station before moving
on to the next station. The stations may
be carried out in any order. No one may
be positioned in or near the target.
However, a person may be designated to
assist in retrieving thrown discs.
- B. Discs: The player shall provide
at least four of his or her own discs as
per section 602.01.
It is advised that an additional disc be
available in the event of damage to one
of the discs.
- C. Time: A total of 7 minutes
shall be allowed for completion of the 28
attempts. A time warning shall be given
at 1 minute remaining. Any throw which is
released after the expiration of the 7
minute period shall be deemed an
unsuccessful throw.
- D. Foul: No supporting point of
the player shall rest on or beyond the
foul lines or their extensions at the
moment of his or her release. A
follow-through motion which crosses the
foul line after the release is
permissible. Any foul shall count as an
unsuccessful throw.
- E. Good Throw: A good throw shall
be made whenever the thrown disc passes
entirely through the target plane from
front to back and a foul or time
violation is not committed.
- F. Scoring: A good throw shall
count as one point. An unsuccessful throw
shall receive no points.
- 603.02 Distance:
- A. Play: The player shall make
five attempts in each round to throw a
disc as far as possible.
- B. Discs: The player shall provide
at least five of his or her own discs as
per section 602.01.
It is advised that an additional disc be
available in the event of a re-throw.
- C. Time: A player shall make all
five of his or her throws within 2 1/2
minutes from the time the signal is given
by the line judge. A time warning shall
be given at 30 seconds remaining. In semi
or final rounds, the format may be
changed to allow simultaneous time
periods. Under this format, players are
given 4 minutes to make all five of their
throws from the time the signal is given
by the line judge. All players throw
during the same time period. In semi
play, two consecutive simultaneous rounds
may be used. A time warning shall be
given at 2 minutes remaining and at 30
seconds remaining. Under either format,
any throw released after the expiration
of the throwing time period shall not be
marked.
- D. Foul: No supporting point of a
player shall rest on or beyond the foul
lines at the instant of his or her
release. A follow-through motion which
crosses the foul line after the release
is permissible. In the event of a foul,
the throw shall not be marked.
- E. Measurement: Legal throws shall
be measured from the midpoint of the
front foul line to the center of the disc
at its point of impact. All throws shall
be measured to the nearest cm.
- F. Score: The length of a player's
longest throw, to the nearest centimeter,
shall be his or her score.
- G. Interference: In the event a
throw is touched while in flight by a
person or animal, the player shall have
the option of counting the throw and
having it measured from the point of
interference, or immediately choosing to
take a rethrow. An additional 30 seconds
will be granted for each rethrow.
- 603.03 MTA:
- A. Play: A player shall attempt to
throw the disc in such a fashion that the
disc remains airborne for as long as
possible, before catching the disc
himself. Each player shall make five
attempts in each round.
- B. Discs: A player shall provide
at least one of his or her own discs as
per section 602.01.
It is advised that an additional disc be
available in the event a disc is lost or
becomes unsuitable for use.
- C. Timing of the Throw: The timing
of the flight of the throw shall be
measured from the instant of release
until the instant the disc is initially
touched in the catching attempt. Time
shall be calculated to the nearest
one-hundredth of a second. The player's
time for a throw shall be the median
(middle) time rating of three time
ratings received from the measurement
crew. In the event that only two times
are recorded by the measurement crew, the
back-up timer's result shall be used as
the third rating. If no backup is
available, the two ratings shall be
averaged. If only one valid time is
available, a re-throw is necessary. No
time shall be recorded for unsuccessful
throws.
- D. Time of Play: A player shall
release a throw within 15 seconds after
receiving a signal to throw from the site
judge. Any throw released after the
expiration of the 15 second period shall
receive a score of zero.
- E. Catch: A catch shall be deemed
valid when the throw is caught and
controlled in one hand by the player,
without the disc simultaneously touching
any other part of the player's body and
prior to the disc touching the ground.
The player is permitted to touch the disc
an unlimited number of times before the
catch is made, as long as he or she only
touches the disc with one part of his or
her body at a time. In the event the disc
touches the ground simultaneously with
the instant the catch is made, the catch
shall be valid. A player shall be in full
control of the disc before he or she lets
it go, changes hands, or touches the disc
with another part of the body for the
catch to be valid. The validity of
questionable catches shall be announced
by the player, subject to review by the
event judges.
- F. Score: The player's score shall
be the single best time recorded.
- G. Groupings: To facilitate rapid
completion of the event, the players
shall be placed in groups of five for the
purpose of alternating the order of
throws. Each player makes one throw, then
the order is repeated until each player
has made his or her five throws in the
round.
- H. Starting Order: In the first round the starting order
is decided by some order of random distribution. In all subsequent
rounds, each player, in descending order according to his or her performance
in the previous round, shall be given his or her choice of throwing
order and site. If two or more players have the same results in the
previous round, the order of choice in the current round shall be
decided by the disc flipping method. See section 104.03.
- I. Interference: Whenever a
catchable throw in flight is touched by
any person or animal, or a player in
pursuit of a catchable throw is impeded
by interference, the throw shall be
declared void and the player shall
receive an additional attempt. Permanent
and/or predictable obstructions, as per section 601.02, shall
not entitle the player to another
attempt.
- 603.04 TRC:
- A. Play: A player shall attempt to
throw the disc from a marked circular
area in such a fashion that the disc
travels as far as possible before
catching the disc himself. Each player
shall make five attempts in each round.
- B. Discs: A player shall provide
at least one of his or her own discs as
per section 602.01.
It is advised that an additional disc be
available in the event a disc is lost or
becomes unsuitable for use.
- C. Foul: No supporting point of
the player shall rest on or beyond the
foul line at the instant of his or her
release. A follow-through motion which
crosses the foul line after the release
is permissible. Any foul shall count as
an unsuccessful throw and shall receive a
score of zero (0).
- D. Measurement: A throw is
measured from the point on the ground
directly under the disc when it is first
touched by the player in his or her
catching attempt, to the closest point of
the foul circle. Readings should be made
to the nearest cm. If the measurement
point falls on or within the throwing
circle, the attempt shall be scored as a
zero (0).
- E. Catches: The rules for catches
set forth in section
603.03(E) of the MTA rules shall also
apply to the rules governing TRC.
- F. Time of Play: The rules
regarding time of play set forth in section 603.03(D) of
the MTA rules shall also apply to the
rules governing TRC.
- G. Score: A player's longest
single throw resulting in a valid catch
shall be his or her score.
- H. Groupings: The rules regarding
groupings set forth in section
603.03(G) of the MTA rules shall also
apply to the rules governing TRC.
- I. Starting Order: The rules
regarding starting order set forth in section 603.03(H) of
the MTA rules shall also apply to the
rules governing TRC.
- J. Interference: The rules
regarding interference set forth in section 603.03(I) of
the MTA rules shall also apply to the
rules governing TRC.
- 603.05 SCF:
- A. Play: SCF combines the events
of MTA and TRC by awarding a single sum
of points based on a player's MTA and TRC
performances. All cuts in SCF events
shall include both MTA and TRC. The rules
governing MTA and TRC shall apply to SCF.
- B. Scoring: A single SCF score
will be determined each round by
multiplying the player's MTA score by a
factor of 5.5 (rounded to the nearest
hundredth) and adding it to the player's
TRC score. For example, a 10.05-second
MTA, worth 55.28 points, would be added
to a 57.41-m TRC performance worth 57.41
points, for an SCF score of 112.69
points.
604 Event Procedures
- 604.01 Judges:
- A. Accuracy: The head judge shall
assign all players to their respective
sites and coordinate all other judges.
The site judge shall be responsible for
timing the players, calling fouls and
recording good throws. If available, a
second person may assist the site judge
in calling hits and misses so that the
site judge may concentrate on foul calls.
- B. Distance: The head judge shall
assign all players to their respective
sites and coordinate all other judges.
The site judge shall be responsible for
timing the players and calling fouls. A
measurement crew, consisting of two
persons, shall be assigned to each site,
working in concert to mark each throw at
its point of impact and assist in
measuring the distance of the longest
throw(s). A statistician shall record all
measured throws.
- C. MTA: The head judge shall
assign all players to their respective
sites and coordinate all other judges.
The site judge shall announce the
players, time their throwing periods, and
determine and record the official time
for successful throws. The measurement
crew, consisting of four persons (three
timers and one back-up), shall measure
the times of the throws with stopwatches.
- D. TRC: The head judge shall
assign all players to their respective
sites and coordinate all other judges.
The site judge shall announce the
players, time their throwing periods, and
determine and record the official
distance for successful throws. The
measurement crew, consisting of five
persons, shall mark each successful throw
and assist in measuring the distance of
the longest throws.
- 604.02 Advancement:
The number of players to advance after each round
shall be determined prior to the start of play by
the number of entries in the tournament.
Top-seeded players shall be evenly spread
throughout the preliminary round. Order of play
in later rounds is determined by performance. See
603.03(H).
- A. Distance, SCF, MTA, TRC:
- (1) Competitions of 30 or fewer:
Prelim - cut to 15 plus ties;
Semi - cut to 5; Final.
- (2) Competitions of 31 to 80:
Prelim - cut to 25 plus ties;
Semi - cut to 5; Final.
- (3) Competitions of more than 80:
Prelim - cut to 50 plus ties; 2nd
Round - cut to 10 plus ties; Semi
- cut to 5; Final.
- B. Accuracy:
- (1) Competitions of 30 or fewer:
Prelim - cut to 12 plus ties;
Semi - cut to 2; Final -
head-to-head.
- (2) Competitions of 31 to 80:

- 604.03 Ties:
- A. Accuracy: If ties must be
broken, the tied players shall have a
head-to-head playoff with the first
player to win a four-throw station
advancing or being declared the winner.
- B. Distance: If ties must be
broken, the tied players shall have a
series of simultaneous throws in a
head-to-head format with the first player
to win three of these one-throw matches
advancing or being declared the winner.
- C. SCF: If ties must be broken,
the tied players shall have a
head-to-head playoff. The playoff shall
consist of one MTA throw and one TRC
throw for each player. These results
shall be combined in the normal fashion
to produce SCF scores. The player with
the higher score advances or is declared
the winner.
- 604.04 Late Arrival:
Players must be at the event site prepared to
compete when called. The competitive order of
these calls is to be posted. In the event of a
player not responding to the official's call, the
following procedures come into effect:
- A. Accuracy: If a player fails to
respond to the official's on deck call,
the next player in the order will be
called. The absent player shall be called
again for the next throwing position. If
he or she responds, he or she may throw
and a two-throw deduction is made from
his or her score. If there is no response
to the second call, the player shall be
listed as a scratch (SCR).
- B. Distance and SCF: If a player
fails to respond to the official's
on-deck call, the next player in the
order will be called. The absent player
is to be called again for the next
throwing position. If he or she responds,
he or she may throw but is only allowed
three attempts. If there is no response
to the second call, the player shall be
listed as a scratch (SCR).
- 605 Glossary
