We do our best to always stick to the courses as published, but please be advised that final course routes are subject to change as determined necessary by race officials and permitting authorities for the safety of all participants. Occasionally there are emergency construction projects or unforeseen road closures that necessitate a an alternative route. Any changes to final course routes will be emailed to all participants in the weeks leading up to the event.
We are still excited for race day, and planning for an exciting day. This is a rain or shine event, please plan for all weather conditions. Be over-prepared, and use your gear check and special needs bags as needed.
All distances will encounter a brief one mile of gravel section between miles along Yellowstone Trail Road about 8 miles from McEuen Park. Piccolo and Centro riders will cross this section once, Medio and Gran riders will cross this section twice.
Due to the nature of the course and riding on highways and freeways, we recommend and strongly encourage to not ride with headphones or earbuds in during the event. This will allow you to hear oncoming riders, traffic, directions from volunteers, and overall return to the finish line safely.
Cell phone reception is poor in some parts of the course. If you lose cell phone service and need immediate assistance on the course, every volunteer and course support vehicle will have radio communications. If you lose cell phone service your Ride with GPS or other map system may disconnect but it will reconnect and reroute once you've maintained cell service again.
The courses will be well marked at all the major turns but we suggest the use of a GPS or use of Ride with GPS on your smartphone for additional confidence in way-finding.
Aid stations will be scattered along the course. Aid Stations will be stocked with water, electrolyte drinks, assorted fruit, and bars. Additionally, the Harrison Aid station will be serving some breakfast and lunch food options. Use your tear tag on your jersey bib number to get your food at the food stop.
**exact locations are subject to change based on final permits and community groups supporting each station.
There will be tech support on the course, but please be prepared since it may take time for them to reach you. Be sure you have everything you need to fix a flat or other bike maintenance issues. We strongly encourage you to make sure your bike is tuned up and ready to go on race day. The majority of our tech issues on course are due to people riding bikes that have not had recent maintenance. Due to recent supply chain issues, bike techs may only have limited parts to help fix your bicycle. Tech support will be available at various aid station locations around the course. If you are unable to get to an aid station for tech support, please call the Negative Split general phone number 208-806-1311.
