All swim courses start at the South Dock, travel clockwise around triangle turn buoys, and finish at the North Dock up into the transition area.

The Bike

Biker with supporters

Beautiful vistas of lakes, mountains, and forest. Out and back for the Olympic course on paved roads with wide bike shoulders. The turnaround is on the flat between the two scenic overlooks above Mormon Lake. The Long Course bike is out and back with the turnaround a mile past the Discovery Telescope near Happy Jack. Long Course has some hills with nothing bigger than a 395 ft climb, and great views of San Francisco Peaks. Long Course bike cut-off is 5:15 hours. You will not be allowed to start the run if you enter transition past this time. Race numbers must be attached to your bike frame. Cyclists are personally responsible for the proper working condition of their bike. Bike helmets are required.

The Run


Out and back run on paved roads along beautiful Lake Mary. Courses climb a decent hill (~ 1mile and 385′) and are otherwise flat. Race numbers must be worn and visible from the front. Water aid stations are every 1.5 miles. Run defensively and follow all instructions of safety personnel. Traffic will not be stopped for this event, except at the intersections and turnarounds, and then at the discretion of the safety personnel. Run elevation graph HERE.

COVID-19 Mitigation Guidelines


FOR SATURDAY PACKET PICK UP AND RACE DAY: If there are spots available (first come first serve), then we recommend parking in the day-use area (all-day pass for $9). You can also park along the road, but be sure to park completely off of the pavement/asphalt. Do not park in any areas with “No Parking” signs posted. This is for the safety of participants, spectators, and drivers. Citations may be given to those in violation. Please give yourself plenty of time in case you need to walk a few minutes to get to the transition area. Sunrise is approximately 5:45 AM, so you may want a flashlight for walking to transition.

Schedule of Events & Logistics

Transition: Opens at 5:45 AM, and closes 15 minutes prior to your swim start. Only athletes allowed in transition. Please be kind and aware of other athletes at all times in transition.

Swim Times and Format:

  • 7:00 AM – Rolling start for all 70.4 Long Course categories. This year will be a rolling start to help provide social distancing, with all male, female, and relay categories lining up together. Athletes self-select their spot in line. We recommend finding a spot according to approximate expected swim time. When athletes get to the front of the line the director will be starting two athletes at a time approximately 5 seconds apart. Please be sure to keep at least 6 feet between you and the people in front of you when waiting in line.
  • 7:30 AM – Rolling start for all Olympic Categories

No wetsuit stripping at this year’s event to help prevent close contact. We hope this can return next year.


Awards ceremonies are contingent on results posting, but we aim to host them at approximately 11:00 AM (Olympic), 12:30 PM (70.4 Overall/Master’s Winners) and 2:00PM (70.4 Age Group).

Course Closure

For the safety of our athletes and volunteers we must adhere to the timing coordinated with permitting and safety personnel. The swim course closes after 1 hour and 10 minutes, the bike course closes after 5 hours and 15 minutes, and the run course closes by 3:00 PM. If an athlete is still on one of the courses at these cutoff times, then they may be asked by volunteers or staff to exit the course, and turn in their timing chip.

Know the Course: Map and aid stations

Be sure to take a close look at course maps (Long Course, Olympic). There is an aid station at the bike out/run out of transition. There are no additional aid stations on the Olympic bike course. There are aid stations at approximately mile 20 (water and Gatorade drink bottles to grab, and GU Gels), and mile 38 (water and Gatorade bottles and GU Gels) of the Long Course bike. There are run aid stations approximately every 1.5 miles on the run courses with water, electrolyte drinks, gels, and snacks.

While there will be volunteers and Rangers to help stop traffic, Lake Mary Road is open to traffic, and it is the racer’s responsibility to follow all course signs and rules of the road. Please ride, run, and drive safely.
