❌Air Quality Index is "poor to unhealthy" and I'm feeling the effects of being outside less than 10 minutes
💯racer, volunteer, and vendor safety is #1 priority and they're still calling for thunderstoms and wind gusts on Saturday.
💯this was a difficult decision. But logistics in rescheduling, communicating, etc., is still less important than your SAFETY.
✅NEW RACE DATE: Sunday, October 25th. The weekend in between Peak 2 Peak and IceMan. Would be a nice warm up race.
✅All registered racers have been emailed. Would appreciate your sharing this and/or sharing with your racing friends.

1st Annual Shelden's BIG Bang XC MTB Race has an awesome course designed by local great Steve Vigneau. 👏👏👍
✅From early on, Steve has been a tremendous help in making this return to Stony Creek a reality, and has so many talents.
💯When it comes to marking this course, Steve has requested nearly 70 signs to make sure EVERY turn and intersection is marked, and it will BE !!

✅Safety is #1 to Join The Fight. Who better to partner with than the Clinton River Area Mountain Biking Bike Patrol !
✅There'll be a Certified First Responders on course marshaling specific locations, a manned tent at the finish and they'll sweep the course to make sure nobody goes un-attended.
✅Thank you Steve Knott, and your GREAT team for your service and love for biking.
