CONCEPT
OF STAGGER: Stagger is a word used in Athletics. It is only used
in track events.
Stagger is the change in starting line and end line
fair equal for all participants.
EXPLANATION:
Stagger is the excess distance covered by the runner from 2nd lane
to 8th lane on their running path in one lap, when compared to the
distance covered by the first lane runner on his running path in one lap.
Formula for find
out the stagger standard track
W(n-1) -0.10 x 2
(W= width of lane n= lane number)
Thus, w(n-1)-.10 x 2
ADDITIONAL INFORMATION
THE FORMULA FOR STAGGER
Half stagger W(n-1) x - 0.10
Full stagger W(n-1)
x-0.10 2
Finding out the CDR and RDR for the Length of the Straight is 84.39 meters in the 400 meters standard track with kerb raised border.
RDR ( Running distance Radius)
CDR (Curve Distance Radius) or (Marking distance
Radius)
Length of the
Straight = 84.39
Each straight = 84.39 + 84.39 = 168.78
Both curve length
= 400 -168.78 = 231. 22
One Curve = 231.22/2 = 115.61
2
RDR = 36.80
CR = 36.80- .30cm
CDR= 36.50
Finding
out the CDR and RDR for the Length of the Straight is 84.39 meters in the 400
meters Non- standard track no kerb without raised border.
RDR ( Running distance Radius)
CDR (Curve Distance Radius) or (Marking distance
Radius)
Length of the
Straight = 84.39
Each straight = 84.39 + 84.39 = 168.78
Both curve length
= 400 -168.78 = 231. 22
One Curve = 231.22/2 = 115.61
2
RDR = 36.80
CR = 36.80- .20
CDR= 36.60
Finding
out the CDR and RDR Length of the
Straight is 40 meters in the 200 meters
Non- standard track no kerb
without raised border.
RDR ( Running distance Radius)
CDR (Curve Distance Radius) or (Marking distance
Radius)
Length of the
Straight = 40
Each straight = 40 + 40 = 80
Both curve length
= 60 + 60 = 120
One Curve = 60
Two curve
=120/2 =60
2
RDR = 19.09
CDR = 19.89
