Coconino Stage Bikepack – Arizona Endurance Series

Coconino Stage Bikepack


October 11-14, 2024

We will be meeting on Friday, October 11, 2024 at 7:00am in Flagstaff, downtown at ‘The Place’ (21 S Milton Rd). We eat a big greasy breakfast, chat a bit and then we ride! The actual starting time for the first stage (and every stage) is open-ended.

The 250-mile route has about 40-50% singletrack, some of which is pretty darn technical, and about 33k of climbing. The route is: Flagstaff-Sedona-Mingus Mountain-Williams-Flagstaff. Those that have never ridden in this area, you are in for a treat!

Live tracking link will be listed at: http://trackleaders.com

Carrying a SPOT tracker is optional. You can add your own SPOT/InReach to the tracking map at the following link (email info@trackleaders.com to inquire about a rental device):


The (old) forum:

GPX: GPS and Cue Sheets can all be found here.  The file CLR22_v2_10k_simplified.gpx is the latest version of the route. The 2013 files are current for the cue sheets and waypoints.

For help uploading the track to your GPS see TopoFusion’s uploading tutorial.

Please note: it is very important that you upload both the GPS track (line) AND the waypoint file. The waypoints define where stages start and end, as well as help everyone regroup at the end of each stage.

Bikepacking.net route description

Self Supported Stage Bikepacking

The Coconino 250 is a self supported stage bikepack. The usual rules for self-supported bikepacking apply (see AZT 300, CTR for examples), with one exception: there are locations on the route where stopping is allowed and as long as you are there, the ride clock is not ticking.

This makes the event into a quasi-stage ride. Riders may ride from one stopping location to another, then rest the night before the next ‘stage.’ However, stopping is not required at any of the points. The option of a non-stop ride is still open.

There are 4 stages, with 3 “stage stop” locations. The first two are camp sites, with no water or other services available (but fantastic views!). The third is the town of Williams, where most racers opt to share motel rooms. You can also camp on nearby national forest, if desired.

Each rider’s time will be computed as = the total time on course minus the total time spent in designated stopping locations. Because of this it is important that you carefully log your time in and time out. Bring a piece of paper to do this, and if you can collect a GPS track for backup, even better.

The idea is to promote camaraderie, lessen the physical ‘impact’ on participants, and also experiment with a new format.

The stage stops are marked as waypoints in the course GPX file and also denoted in RED on the cue sheets.

Aspen Asphyxiation-Arizona Endurance Series

At 8:00am on Saturday, June 1, 2024

Start/End at Fort Tuthill, big lot next to the Bike Park.

Aspen Asphyxiation is back in 2023 with a new route and new trails. We will start at Fort Tuthill and then shortcut through the city to Elden via Sinclair/AZT. We will then climb up the brand new Lower Brookbank and descend the gnarly Big Band/Afterglow. We will climb Dogfood and fire/flood survivors: AZT and Secret. We will connect via Freidlein Prairie Rd, Veit Spring Trail and Snowbowl Rd to Aspen Corner. From there it’s a fun descent on AZT and Moto. We will venture into the unknown by means of Hidden Hollow Road, Mesa Observatory forest service roads and A1 Mountain Rd. We will cross the railroad tracks via an interesting but straightforward solution. Then it’s on to Soggy Bottom Ranch Rd. to uncharted roads all the way to Rogers Lake Connector trail. Good ole FUTS and Soldier trail will take us back to Fort Tuthill.

Water available for filtering only in Shultz Creek and Roger’s Lake (and a number of small streams which may or may not still be there by next week).


Start time and route are provided here and it is up to the participant to understand the route, and also have full responsibility for their navigation and well being. Since the events are self-supportive, it should be understood that these are for experienced adult backcountry cyclists only. If you question your ability to complete such an event, it is best that you consider another option before trying one of these. Also, maps, gps devices, water filtration units, and other backcountry tools are methods to ensure you complete the race. Therefore it is up to you – and you alone – to ensure your safety!!
