❌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.
