El Tour de Tucson: Training Guide
Arizona’s biggest day on the bike — a hundred miles of desert roads in a huge November field.
El Tour de Tucson is Arizona’s largest mass-participation cycling event, run each November out of downtown Tucson with several thousand riders on the road at once. The flagship route is roughly a hundred miles across the Sonoran Desert, with shorter options for riders who want a smaller day, and it draws everyone from first-time century riders to fast club racers chasing a finishing time.
For most of the field the goal is simply to finish a long day comfortably and enjoy the scale of the event. The climbing is modest for the distance, which makes El Tour less about brute force on the hills and more about aerobic durability, riding smart in big groups, and managing the desert and the clock over five to seven hours.
What makes it hard
- Distance and aerobic durability. A hundred miles is a long time in the saddle; the limiter for most riders is holding a comfortable, steady effort for five to seven hours, not any single climb.
- Big-group riding. With thousands of riders, the early miles are crowded and fast. Knowing how to sit in a bunch, hold a wheel, and stay calm and safe in a large pack saves enormous energy — and avoids trouble.
- Desert sun and dry air. Even in late November the Sonoran sun and very dry air pull fluid out of you faster than you notice; hydration and electrolytes matter more than the cool morning suggests.
- Pacing in a fast field. On flat-to-rolling roads it is easy to get swept along above your sustainable effort early, then fade in the back half. The day rewards riders who hold something in reserve.
- River-wash crossings and handling, if present. The route has historically included a few sandy wash crossings where riders slow, dismount, or run a short section — check the official site for the current course and ride them cautiously.
What the day actually demands
El Tour is fundamentally an aerobic-endurance day rather than a climbing test. With only a few thousand feet of elevation over a hundred miles, the question is not how hard you can climb but how long you can hold a steady, repeatable effort and keep fueling while you do it. The riders who finish strong are the ones whose endurance base lets them sit at a comfortable tempo for hours without the effort creeping upward.
Because the field is so large, a big part of the day is riding efficiently in a group. Sitting in a well-organized bunch can cut your effort dramatically compared with riding alone in the wind, so the social and tactical side — finding wheels, taking sensible turns, staying relaxed in a crowd — is as much a part of preparing as the intervals.
How to build toward it
Plan roughly 10 to 14 weeks building from an aerobic base toward a comfortable hundred-mile day. The backbone is a steadily growing long ride — push it toward the route’s distance so the volume is familiar — plus regular endurance miles through the week to build the durability that carries you through the back half.
Add some tempo and sweet-spot work so your “all-day” pace feels easy, and if you can, do a few group rides before the event to rehearse riding in a bunch. If you train solo or in flat terrain, long steady rides into the wind are good preparation for the exposed desert roads and the sustained, low-drama effort El Tour asks for.
Fueling and hydration
Aim for roughly 60–90 grams of carbohydrate per hour and start eating and drinking early — on a five-to-seven-hour day it is easy to fall behind and pay for it late. The desert makes hydration the limiter to watch: the dry air and sun dehydrate you faster than the November temperatures suggest, so drink to a plan, use electrolytes, and know where the aid stations are.
Practice your fueling on your long training rides rather than trying anything new on the day. Carry enough to bridge the gaps between stops, and top up fluids at aid stations even when you do not yet feel thirsty.
Equipment and terrain
A standard road bike is the right tool; tires with a little volume and modest tread can help on any sandy wash crossings without slowing you on the pavement. Bring layers for the cool desert morning that you can shed as the day warms, and sun protection for the exposed hours that follow.
Courses, distances, and the exact crossings change from year to year, so always check the official El Tour de Tucson site for the current route, start procedures, and any cut-off times before you finalize your plan.

Common questions
How long does it take to finish El Tour de Tucson?
For the full ≈102-mile route, many riders finish in roughly five to seven hours of riding depending on fitness, the wind, and how much time they spend at aid stations and any wash crossings. Riding in a group rather than alone can make a real difference to both your time and how fresh you feel at the finish.
How many hours a week should I train for El Tour de Tucson?
Many amateurs prepare well for a flat-to-rolling century on roughly six to ten hours a week, with the long ride growing toward the route’s distance over the final weeks. Consistency across the block matters more than any single big week.
Is El Tour de Tucson a race or a ride?
It is a timed mass-participation event with a competitive front end and a huge recreational field behind it. Most people ride it as a personal challenge or charity ride and pace it as a long endurance day, while faster riders treat the front groups as a race. Either way, the training that gets you there comfortably is the same: aerobic endurance, smart pacing, and solid fueling.
