The run course is 2 loops equaling 13.1 miles. Once you drop off your bike you will run back down the transition area towards the road and make a left hand turn. Be careful for any bikes that might be on the road throughout the run portion off the race. You will run 1.7miles east to the 1st aid station. At this point you will then cross the road and continue back towards the start of the race. Please use caution when crossing the street. You will run pass the start of the race and continue down the road for an additional 1.5 miles where there will be another aid station. You will then cross the road again at this point and continue back to the start and then do that same course again. Once you have finished your second lap you will proceed to the finish line and complete the Sourdough Triathlon. The run course is a flat course however there is very limited shade, so be prepared for it to be hot and for you to be exposed to the sun and elements. While there is no course completion cut-off time, aid stations are only staffed until 6:00 pm.
