No Pogacar. No Vingegaard. For the first time since 2023, the Race of the Two Seas doesn’t have a predetermined winner, and the GC fight should actually be interesting all week.

Tirreno-Adriatico 2026 runs March 9-15 across seven stages from the Tyrrhenian coast to the Adriatic. The numbers: 15,550 meters of climbing, up 950m from 2025’s edition. 16 classified climbs. Three hilly finishes. A short opening time trial. And a startlist built around riders who can all realistically win.

That combination makes this edition worth studying, not just for the racing, but for what the stage designs and rider demands tell us about training in mid-March.

Why the Wide-Open GC Matters

When Pogacar or Vingegaard race Tirreno, the GC goes one way. The dominant rider controls the mountain stages, and everyone else races for second. The tactical lessons are limited because the outcome is mostly about raw power advantage.

Without them, the 2026 GC contenders are closer on paper. Isaac del Toro is the bookmakers’ pick, a pure climber with a solid time trial. Van der Poel brings his usual mix of power across every terrain type but hasn’t targeted a week-long GC in Italy before. De Lie has been building toward stage racing after years as a punchy sprinter-turned-classics rider.

The racing should be more aggressive. When no single rider can control the race on the climbs alone, stages get harder earlier. Attacks come from further out. The pacing across days becomes the real skill test, because you can’t just follow one wheel and know you’re safe.

For amateur riders, that’s the more useful model anyway. Your local stage race, your multi-day sportive, your back-to-back weekend centuries don’t have a Pogacar to follow. You have to make your own pacing decisions across days of accumulated fatigue.

Stage 1: The Short Time Trial and What It Reveals

The opening stage is a flat time trial in Lido di Camaiore. Short, probably under 15 minutes for the pros. Not long enough to create huge GC gaps, but long enough to separate riders who’ve worked on their TT position from those who haven’t.

Here’s the training takeaway: short time trials reward riders who can produce high power immediately.

In a 40km TT, you settle in. The first 5 minutes matter less because you have 45 more to pace correctly. In a short TT, the start effort is a larger percentage of total time. Getting up to speed, finding your rhythm, and holding just below redline for 12-15 minutes is a specific skill.

If you haven’t done a short time trial effort since last season, try this:

Short TT Opener Workout

• Warm-up: 20 minutes building to Zone 3
• 3 x 12 minutes at 95-100% FTP, 5 minutes easy between
• RPE: 8/10. Sustained hard, not maximal. You should be able to hold the effort but be glad when each one ends
• Focus: The first 90 seconds of each effort. Practice hitting target power within the first minute, not drifting up to it over 3-4 minutes

That first-minute discipline is what separates a good TT result from a mediocre one. Most amateurs start too hard and fade, or start conservatively and never find the right intensity. The pros opening Tirreno with this stage will have rehearsed their start power dozens of times.

15,550 Meters of Climbing: The Cumulative Load

The climbing numbers for this edition are significant. Nearly a thousand meters more than 2025, distributed across every stage after the time trial. That’s not one big mountain day followed by recovery. It’s climbing every day for six straight stages after the TT.

For the GC contenders, managing that cumulative load is the race within the race. Del Toro’s advantage on any single climb might be 10-20 seconds. But if he recovers better between stages, eats better, sleeps better, that advantage compounds. By stage 5 or 6, the rider who managed the early stages most efficiently has a leg up that doesn’t show in any single power file.

The amateur parallel: your Saturday ride affects your Sunday ride affects your Monday commute.

Most of us train stage-to-stage fatigue accidentally. We ride hard Saturday, feel flat Sunday, and call it a bad day. But the pros at Tirreno are deliberately managing their output across seven days. They know exactly how hard they can ride Tuesday and still have legs for Thursday’s mountain finish.

You can train this deliberately with back-to-back loaded weekends:

Cumulative Load Weekend Block

• Saturday: 3-4 hours with 1,200-1,500m climbing. Ride the climbs at tempo (Zone 3, RPE 6/10). Not race pace. Controlled.
• Sunday: 2.5-3 hours with 800-1,000m climbing. Same tempo effort on the climbs. Pay attention to how much harder the same power feels on day two.
• The point: Learning what “sustainable across days” actually feels like in your body. It’s lower than you think.

If you did the spring classics base-to-race training block in February, your endurance base can handle this. If you’re coming off an indoor-heavy winter, start with two-hour days and build from there. The early season race prep guide covers the ramp-up timeline.

The 16 Classified Climbs: Repeated Efforts, Not Singular Tests

Sixteen climbs across a week means the average stage has two to three classified ascents. These aren’t all massive. Some are short punchy rises, 2-4km at moderate gradient. Others are longer sustained efforts.

The pattern matters more than any individual climb. Racing over repeated short climbs demands a specific fitness: the ability to push above threshold for 5-10 minutes, recover partially on a descent or flat section, then do it again. And again.

This is different from one big 45-minute climb where you settle into a rhythm. Repeated climbs ask you to surge, recover, surge, recover. Your body processes lactate during the recovery valleys, and the riders who clear it fastest are the ones who can push hardest on the next rise.

Climbing Repeats Session

• Warm-up: 15 minutes easy
• 5 x 6 minutes at 105-110% FTP (Zone 4-5, RPE 8-9/10), with 4 minutes easy spinning between
• Cool-down: 10 minutes easy
• Total structured time: ~65 minutes
• When: Once per week, replacing one of your harder interval sessions
• Why it works: Simulates the repeated climbing demands of a hilly stage. The 4-minute recovery is just enough to partially clear lactate but not fully recover, which is exactly the gap between climbs in a race

If you have a local climb that takes 5-8 minutes, do these as hill repeats outdoors. The grade forces honest effort in a way the trainer doesn’t always replicate.

Three Hilly Finishes: The Last 5km Problem

Three stages end on or just after climbs. These are where the GC contenders will reveal themselves. The effort pattern is specific: ride conservatively for 4-5 hours, then produce your best power in the final 10-20 minutes when fatigue is highest.

Van der Poel is built for this. His ability to produce massive short-duration power after long days is documented. Del Toro’s climbing advantage may show earlier in stages but might not survive a short punchy finish if Van der Poel is on his wheel.

For amateurs, the final-climb problem is familiar. You’ve done it on every group ride where the sprint for the city limits sign happens after three hours. The riders who win those sprints are either the freshest (they sat in all day) or the ones who specifically train end-of-ride power.

You can add this to any long ride:

End-of-Ride Punch

• In the last 30 minutes of your longest weekly ride, find a short climb or headwind section
• Do 2 x 3 minutes at VO2max effort (Zone 5, RPE 9/10), with 3 minutes easy between
• The tired legs are the point. You’re training your body to produce power when glycogen is low and fatigue is high
• This mirrors what the Tirreno GC riders face on hilly finishes after 150+km in the saddle

Pair this with solid fueling strategy. If you haven’t dialed in your on-bike nutrition, the indoor training nutrition guide covers caloric timing that applies to outdoor rides too.

Pacing Across a Week: The Real Skill

The riders who lose Tirreno don’t usually blow up on one stage. They lose 15 seconds here, 20 seconds there, across multiple days because they burned matches early in stages that didn’t matter or didn’t recover aggressively enough between stages.

Amateur riders make the same mistake in compressed form. You go too hard on Tuesday’s intervals, feel flat for Thursday’s group ride, and wonder why you can’t hold wheels you normally stick with. The week is a system. Training days interact with each other.

If you’re racing or riding events on consecutive weekends this spring, use the Tirreno model:

• Monday after a hard weekend: Complete rest or 30 minutes of genuinely easy spinning. Not “active recovery that accidentally becomes Zone 3.”
• Tuesday-Wednesday: One quality session, one easy day. Not two quality sessions.
• Thursday: Easy. If your legs feel surprisingly good, still go easy. Banking recovery for the weekend pays off more than one extra interval session.
• Friday: Short opener. 15 minutes with a few 30-second accelerations to wake up the legs.
• Weekend: Your target rides or events.

That pattern looks boring on paper. It works because it respects cumulative fatigue, which is the central challenge of any multi-day cycling effort, whether it’s a WorldTour stage race or your own training week.

Who Wins?

Prediction time. Del Toro has the climbing pedigree and the TT ability. Van der Poel has the power and the tactical intelligence but hasn’t won a week-long stage race. De Lie is the dark horse with the trajectory.

The time trial probably doesn’t create enough gaps to decide GC. The climbing stages will. And with three hilly finishes plus 15,550m of total elevation, the rider who paces the best across all seven days wins. That’s del Toro’s race to lose.

But the real winner for amateur cyclists is the race format itself. A week of racing that rewards pacing discipline, repeated climbing ability, short TT power, and end-of-ride punch. Those are trainable qualities. Every workout in this article targets one of them.

Pick the one that matches your weakest link. If you handled the Paris-Nice training takeaways well, add the cumulative load weekends and the climbing repeats. If you’re still building base fitness, focus on the back-to-back weekend rides and the end-of-ride punches.

March is for building. Tirreno-Adriatico shows you exactly what to build toward.
