Race Day, Saturday, August 22,

Welcome to the Home of the

25th Seeley Lions Club PreFat Mountain Bike Race!

Event Update – May 8, 2020

We have not given up on the 25th Annual PreFat Mountain Bike Event even in these very uncertain times.  The PreFat remains scheduled for August 22.

We will continue to listen to health authorities and monitor what is happening with the pandemic.

We’re hopeful that an event is possible, but your safety and our safety are the top priority. As soon as we decide the best course of action to follow, we will let everyone know.  We hope to be in a better position to make a decision in early June. Registration will not open until there is a high level of confidence the race can proceed as usual, or we determine other options which would not compromise anyone’s safety. 

Keep the PreFat event on your calendar and be safe.
