NEW IN 2026: We intend to host a TCM-specific training group beginning May/June. It will be similar to the RunFest's training group.
Weather:
October weather in Tri-Cities is variable. While there is a general range most days fall under, you should be prepared for any conditions.
Typical Late October Day: 40-55F, Overcast, winds blowing east, low chance of rain.

2024: 58F at start, 20mph sustained winds east.

Volunteers!!!
No organized running event would be possible without the help of volunteers. Between aid stations, course marshals, event setup, etc., we will need about 70-90 volunteers to make this event the best it can be, and of course any extra help we can get is greatly appreciated. Have family/friends not doing anything on a Sunday morning? Bring them out with you to help you and fellow runners on your way! (Did I mention fresh air is good for everyone?)
