​16K (10 miles) only - 2 loops of the 8K course

8K only

3K only


If you take on the "Challenge", you'll run three event phases in this order: An 8K with a climb and descent, a 1.5K trail sprint with a short climb and fast descent, and a 3K flat and fast loop.  After all Challenge participants have completed the 8K, results will be posted.  Then, all Challenge participants will start their 1.5K trail sprint in the order that they finished the 8K, taking off at 15 second intervals.  After all Challenge participants have completed their 1.5K Trail Sprint, results will be posted and there will be a 5 minute rest period before the 3K final leg takes off with a staggered start. Challenge participants receive overall and age group points from each of the three phases, and then awards are based on the lowest combined scores.  What this means is that there's strategy with each phase - the end results are not based on total time, so if someone in your age group is pulling away from you on a phase, you could conserve some energy for the next phase, since the scores are based on placing.  Participants in the Challenge will keep the same bib number with their timing chip for all three phases.
