Donner Lake Triathlon Sprint

The Sprint swim course is 1/4 mile in Donner Lake with two left turns. Corners are marked by large buoys and kayakers/boats are along the course to ensure your safety. The average water temperature of Donner Lake in July is 64-69 degrees. Wetsuits are optional. The swim course maps are posted on our Course Maps page.
The bike course takes place on Old Highway 40. The entire course is paved.
The Sprint bike course is 6 miles total- 3 miles each way up to Donner Summit and back. The total climb on the bike for the sprint course is about 975’. The turnaround point is at the view area on Rainbow Bridge (will be well marked and staffed on event day). There is no aid station on the sprint bike course and athletes are encouraged to bring a full water bottle with them on their bike.
The Sprint run course features a 2 Mile out-and-back run on South Shore Drive. Triathletes leave the transition area on the South side of the parking lot. You will pass two aid stations while on the run: one as you leave the transition area and the other at the turn-a-round point.
The Foot Down Bike Stop: Whether you are competing in the Sprint, Olympic, Aquabike, or Half distance, you will be required to perform a foot down stop at the bottom of the descent, before continuing on to re-enter the transition area. A foot down stop means one of your feet comes out of your bike clips (or off your pedal) and rests on the ground in a designated spot while your bike is at a complete stop for a minimum of 3 seconds. The reason for the foot down stop is a purely a safety issue. Should the foot down not be enforced, we would be cleaning up cyclists’ carnage as they attempted (unsuccessfully) to make the 130 degree turn back into the transition area at 45 mph. Everyone has to do the foot down stop so there is no advantage/disadvantage for anyone. Failure to comply will result in a DQ and there are absolutely no exceptions.
Mount/Dismount Area: At the Donner Lake Triathlon, you are not permitted to ride your bike in the transition area. There is a mount and dismount area outside of the bike start/bike finish tents.
