About the Course

The Swim
A 1.2 mile open water lake swim. Wave starts (approximately 100 per wave), rectangular course counter clockwise, entry at beach area and exit on cement boat dock area, within 20 yards of the transition area. Swim cutoff time is 75 minutes.

Note: The water temperature in Buffalo Springs Lake, on the average, is 70-74 degrees (even during the 113 degree day of 1994 the water temperature was never over 74 degrees). It is a spring fed lake so it stays cool; therefore, you should bring your wetsuits. USAT wetsuit rules apply: wetsuits are allowed with 78 degrees or cooler.

The Bike
