Most riders who finish a Grand Tour spend the next month doing as little as possible. Quinn Simmons is spending his at altitude, on a mountain bike, chasing a race he hasn’t touched in seven years. On August 15, less than three weeks after finishing 18th overall at his fourth Tour de France, Simmons lines up at the Leadville Trail 100 MTB — 102.1 miles of Colorado high country, most of it above 10,000 feet.

That’s not a typo and it’s not a recovery ride that got out of hand. It’s the plan.

We’ve spent this season writing about how Grand Tour riders manage the gap between goal events — Pogačar’s four-week turnaround into a second Grand Tour being the obvious recent example. Simmons is running a different experiment entirely. He’s not tapering into another road race. He’s using an off-road ultra-endurance event as the bridge between the Tour de France and the Road World Championships in Montréal — and there’s a real framework in there for anyone who has ever wondered whether a gravel century or a local MTB race counts as legitimate training after a big goal event, or just a way to waste the fitness you spent months building.

Why This Isn’t a Recovery Block

Read that gap again: under three weeks off the back of a Grand Tour. Recovery weeks matter precisely because three weeks of racing at that level digs a hole — fatigue, immune suppression, joints that have taken a beating on 21 stages of pavement. A rider stepping straight into a 100-mile mountain bike race with 9,916 feet of climbing at altitude, that soon, isn’t resting.

But Simmons also isn’t training for Leadville the way Keegan Swenson trains for Leadville. Swenson is the reigning UCI Marathon MTB world champion and the five-time defending Leadville champion — he’s built his whole season around this race and the Life Time Grand Prix series it belongs to. A sixth win would tie David Wiens’ all-time record. Simmons has raced Leadville exactly once, seven years ago, as a teenager who finished second on raw engine and no real MTB-specific preparation. He’s not walking in to beat Swenson on Swenson’s terms. He’s walking in with WorldTour engine and seven-year-old off-road skills, at altitude, on tired legs, three weeks after a Grand Tour.

That’s the part worth sitting with. According to Domestique Cycling’s report on his plans, Simmons is treating the Road World Championships in Montréal — where he calls the demanding circuit “basically our home Worlds” — as the actual target for the rest of his season. He was in the final there last year despite roughly 4,000 meters of climbing on the course, and he’s coming off a third-place finish at the 2025 Grand Prix Cycliste de Montréal and fourth at Il Lombardia. One-day racing sharpness, not stage-race durability, is what he’s building toward. Leadville sits in the middle as something closer to a hard, engaging, low-stakes stress test than a taper race.

The Course, and Why the Details Matter

The 2026 route isn’t the Leadville course longtime fans know. According to Cyclingnews’ coverage of the reroute, the Willow Fire damaged enough of the traditional route that organizers pulled the iconic Powerline climb — a brutally steep, punchy section that’s been part of the race’s identity since the 1990s — and replaced the lost mileage with flatter terrain and pavement around Turquoise Lake. The result is 102.1 miles and 9,916 feet of climbing, a meaningful reduction from the 12,000-plus feet of past editions, though the course still tops out near 12,400 feet at the Columbine Mine turnaround. Less brutal on paper. Still altitude, still six-plus hours in the saddle for the pros, still a completely different physical demand than a road stage.

There’s also an equipment wrinkle that’s oddly on-brand for this race. Life Time banned drop-style handlebars on MTBs at Leadville and its other Grand Prix events for 2026, citing rider safety and course compatibility — a rule Swenson himself has been vocal in supporting, despite having won two of his five Leadville titles on a mountain bike fitted with road-style drop bars. Every competitor, Simmons included, lines up on flat or riser bars this year. It’s a small detail, but it matters for the cross-training argument: this isn’t road racing with knobby tires. The bike handling, the body position, the braking — all of it is a genuinely different skill than what got Simmons through three weeks of the Tour.

How Should Amateurs Use an Off-Road Event as Cross-Training After a Big Race?

An off-road event works as post-goal-event cross-training when it’s timed 2-4 weeks after your main race, ridden well below your climbing or road threshold, and chosen for skill development rather than a competitive result. The physical demand is different enough to count as active recovery for road-specific muscles and mental patterns, while still keeping you engaged and fit.

1. Pick something 2-4 weeks out, not immediately after. Simmons’ three-week gap is short even by his standards — most amateurs are better served waiting closer to four weeks after a truly demanding goal event before adding a hard off-road day. Recovery still comes first; the off-road event is what fills the back half of that window, not a replacement for it.
2. Choose a discipline your road training doesn’t touch. Gravel and MTB demand bike handling, line choice, and upper-body engagement that structured road intervals never build. We wrote about descending as a genuinely trainable skill rather than raw talent — off-road riding is the same idea applied to an entire discipline, not just one skill.
3. Ride it for engagement, not a number. The value isn’t in threshold work. It’s in staying motivated to ride during a period when your legs and head both need a break from structured road training. If you’re checking a power meter obsessively, you’ve turned recovery into another goal event.
4. Expect it to feel hard anyway. Different muscle recruitment, technical demands, and often altitude or terrain your road legs aren’t used to means an “easy” off-road day can still leave you more fatigued than expected. Treat the effort as unpredictable and back off if it’s clearly compounding fatigue instead of dissipating it.
5. Keep sight of what’s actually next. For Simmons, that’s Montréal. For most amateurs, it’s whatever comes after the off-season — base building, or a fall goal event. The off-road race is a bridge, not a destination. If you find yourself building a whole new training block around it, it’s stopped being cross-training and become a second goal event, which is a different problem with its own rules.

What This Actually Looks Like for a Time-Crunched Rider

Say you just finished your goal century or gran fondo and you’ve got a local gravel race or MTB event three to four weeks out that you’ve always wanted to try. Here’s roughly how to sequence it against the recovery-week principles we’ve written about before:

Week 1 after your goal event: Full recovery. Easy spinning only, no structured intensity, the same as you’d do heading into any down week. Don’t let excitement about the upcoming off-road event pull you into early intensity — this is the week that determines whether the next month goes well.

Week 2: Reintroduce some structure, but keep it aerobic. Zone 2 riding dominates. If you’re mixing in dirt or gravel, this is a good week to do a low-stakes shakedown ride on the actual bike and terrain you’ll race, purely to knock the rust off handling skills.

Week 3: One or two slightly harder efforts if your legs are responding well — nothing near threshold, more RPE 6-7 work that mimics the sustained, moderate-intensity grind of an ultra-endurance event rather than the short, sharp intervals of road racing. This is also when you dial in gearing, tire choice, and nutrition strategy for the terrain.

Race week: Show up and ride it for what it is — a different kind of hard, not a peak performance. If you cross the line and your legs are trashed for road training the following week, that’s fine. That’s what a stress test is supposed to do. Adjust your return-to-road timeline accordingly rather than assuming you can jump straight back into structured intervals.

Where This Goes Wrong

Not every off-road detour is smart cross-training, and it’s worth being honest about the failure mode. Ride it too hard, too soon, and you’re not cross-training — you’re stacking a second hard effort on top of incomplete recovery from the first, which is exactly the mistake that can turn a smart bridge into a setback heading into whatever comes next. Simmons has a WorldTour support team managing his load in ways an amateur juggling a job and a training plan doesn’t have access to. The instinct to treat this as license to race hard three weeks after your own goal event, just because a pro did it, is the wrong lesson to take from this story.

The right lesson is narrower: an off-road event, chosen deliberately and ridden below your limit, can occupy the same space in your calendar that a recovery block would — keeping you on the bike and engaged — while building skills your road training never touches. That’s genuinely useful. Racing it like it’s the actual goal is not.

The Bottom Line

Simmons isn’t at Leadville because he thinks he’s the favorite. Swenson’s course record, his marathon MTB world title, and five straight wins make him the clear favorite regardless of what shape Simmons shows up in. Simmons is there because a hard, different, low-stakes day on a mountain bike is a genuinely useful way to spend three weeks that would otherwise be pure downtime before a Worlds course he’s already targeting.

Most of us don’t have a Grand Tour on the calendar or a home Worlds bid in Montréal. But the pattern translates: after a goal event, the choice isn’t only between hard training and doing nothing. A well-timed gravel or MTB day, ridden for skill instead of a result, can be its own kind of recovery — one that keeps you fit, keeps you engaged, and teaches your bike handling something your usual road routes never will.
