All route maps are posted at Ride With GPS. Get the mobile app from the App Store or Google Play. Click links on this website, or search for "2025 DAM JAM."
Ride With GPS integrates nicely with Garmin, Wahoo, Strava, and other devices and services.
Get more route details on the Routes and Maps page.
We'll also have paper maps for those of you who prefer an old-school experience.
One mass start at 8:00 a.m. Police will escort the riders through two significant intersections on their way out of Pryor.
First is a left onto Carbide Road with fast traffic and drivers who won't expect bicycles
Second is across Highway 20, with four lanes and a median, 65+ mph traffic
If you start any time besides the 8:00 am mass start, you won't be escorted, and you must obey all traffic signs and signals
If you leave earlier than 8:00 am, you might find yourself without rest stops or route support. Your call.
Numbered Bibs - The numbered bib we issue you must be worn on your back, plainly visible, so SAG drivers can identify you from their vehicle. Your registration information is tied to your bib number and is how we can identify you discreetly on-air in all support communications.
Directional Support - All routes will be surface-marked with yellow paint. Directional signs will be at key locations. Use the Ride With GPS app / 2025 DAM J.A.M. maps as an orientation aid. Routes are subject to change without notice.
SAG & Communications Support - We have a great team of amateur radio operators serving as SAG drivers, with lots of experience monitoring safety and providing rolling support on bike rides. You'll see them regularly and may utilize them as needed.
Carry your phone - We'll monitor a Rider's Emergency Phone in our SAG communications trailer. If you need help while riding, call the number we'll provide you with before the event.
Mechanical Support - We'll have limited breakdown assistance on all routes. Full mechanical services will be limited. So...
Please be equipped to fix your own flats, put your chain back on, etc., and know how to do it.
Medical Support - There will be no dedicated medical support staff on the course. Most SAG drivers will carry basic first aid kits, but SAGs are not qualified or authorized to provide medical aid. In any medical situation, SAGs will advise radio communications control operators, who will contact Mayes and Delaware County emergency medical services for assistance.
Support Ends - Road support and rest stops close by 4:00 p.m. If you are still riding at 4:00, we'll give you the option to continue unsupported or take a SAG ride back to the start/finish.
Helmets are required for every rider, no exceptions.
No headphones or other distractions.
All riders under 16 must be accompanied by an adult.
Carry water with you... and drink it.
Expect automobile traffic. All routes are on open public roads, with no special traffic control for this event. Obey all vehicle laws. Ride no more than two abreast. Be alert to traffic (see the note above about headphones and other distractions).
Please don't cross the centerline, ESPECIALLY ON HILLS!! Every year, we see some of you do it, and we're amazed you're still alive.
Pass on the left. Signal your moves. Use standard warnings to other riders... "bike on your left", "car back", "car passing", etc. Yield to faster riders, especially on hills.
