Participant Guide & Packets

Every participant will receive a number bib to wear during the event so you can be easily identified.  When you register, you will have the option to pick your preferred location to pick up the packet containing the number bib and other important information.  We will send an email communication approximately one week before the event day confirming where you can pick up your packet.  For those that cannot collect their packets in advance, we'll also have them available the morning of the event.

Fine Print

Registration is non-refundable and non-transferable. Venus de Miles is a rain or shine event; however, in the event of severe weather, your safety will be our number one priority.  

Rider and spectator parking is only available at Creekside Business Park (1921 Corporate Center Circle OR 1811 Pike Rd., Longmont). We ask our riders to respect the local business of Prospect Park and realize that there will be NO EVENT PARKING at Prospect Park.

We encourage you to sign up for the ride that you are capable of completing. August can be hot, and that can affect your ability to finish a course. Our SAG vehicles are NOT meant to give rides back to the finish, please plan to finish your chosen course on your bike.
