The Fly by Night run course follows roads and pathways along the infield of the race track itself. Athletes will have views of the track and the fertile farmland and gorges of the valley beyond.

The run course begins flat and fast down Pit Row before turning towards the infield, through the pedestrian tunnel under the race track, and finally over the footbridge back onto the track at transition.

The run loop is 1.7 miles long and you will complete the loop three times - once for each leg of the race. Total running distance for the entire race is therefore 5.1 miles.

The Fly by Night bike course takes place entirely on the twisting, turning race track of Watkins Glen International.

The track varies from 36' to 48' wide and has a 6° bank at all turns except turn 9S/5L, which is 10°. Elevation changes from a low of 1,460' above sea level to 1,575', including one larger hill in "The Boot."

One loop around the race track is 3.4 miles long and you will complete the loop three times on every bike leg. There are two bike legs in the race, making the total biking distance for the entire race 20.4 miles.
