Rogers returns from point F to point A, along the E-F route to restart? Not exactly sure this would be possible, based on the running speed shown. Even though Rogers is in what seems to be a continuous sprint for the duration. If 3 circuits is 13.98 miles, that's nearly 28 miles an hour. 28 mph is a mile in just over 2 minutes.
I ran Track & Cross Country so here's a further running breakdown:
Rogers average time (based on circuit completion, not accounting for finish to start segment)
1 mile, 4 laps (approx 1600meters): 2 minutes.
1/4 mile, 1 lap (approx 400meters): 30 seconds.
100meters, 1/4 lap (shortest sprinting segment): 7.5 seconds.
World Record for 100 meter dash: 9.58 sec.
Therefore Rogers MUST maintain an average greater than a 7.5 sec 100 yard sprint for over 14 miles. (which for Captain America sounds awesome) BUT, if other experts examine his running speed in each clip, I doubt he's moving quite that speed.
