Gravel Scavenger Hunt
Six checkpoints in any order, two things to bring back, and a 3pm deadline. The first 5 riders to hit every checkpoint won prizes from Sweet Protection and Cassiopeia, with refreshments from Oskar Blues, Suerte and Tailwind.
Let's do this!
How it worked
Below you will find 6 checkpoints you have to reach. You can reach them in any order. When you get to a checkpoint, take a photo of yourself to prove that you made it there.
You ALSO must bring back two items:
- A pinecone that is at least 4 inches tall
- A sticker from the A-Lodge
Please obey traffic rules. Do not ride on Broadway, 28th, Canyon or any other busy road.
Want a route to the checkpoints? Here it is, around 35 miles if ridden efficiently. Want a shorter route with less climbing? This one covers 5 of the 6 checkpoints.
You have until 3pm to return to Cassiopeia.
