The Valencia 70.3 Bike Leg: 90 Rolling Kilometers, Wind, and Watt Discipline

The course at a glance

Don't be fooled by Valencia's reputation as a flat city. The Valencia 70.3 bike leg is 90 km in a single loop with 595 m of official elevation gain, from Malvarrosa beach inland toward the Sierra Calderona and back, with T2 at the City of Arts and Sciences. A rolling profile: fast sections alternating with higher stretches, with long straights and areas exposed to variable wind.

595 m over 90 km averages out to roughly 6.6 m/km. Translation: there are no climbs that break the race apart, but there's also not a single kilometer where you can switch off. It's the kind of course that punishes riders who go by feel and rewards those who ride to power.

The real opponent: the wind

The technical guide and race reports agree on one point: the exposed sections with variable wind are the number one variable of the day. An April race on the Mediterranean means unpredictable conditions, and long open straights mean that when the wind is up, you feel it for kilometers.

The practical rules:

• Into a headwind: steady watts, never surges. A 30-second spike to "get through" a windy section costs a lot and gains almost nothing. Several race reports note that consistency pays off here more than anywhere else.
• With a tailwind: don't give anything away. Hold your aero position and your target power even when you're moving fast. This is where you pick up free time.
• A dialed-in aero position. On the long straights, the difference between holding your position and sitting up is worth minutes, not seconds.

How to manage the climbing

The ramps toward the Sierra Calderona aren't walls, but they need managing:

• Stay seated on most of the gradients. Getting out of the saddle in a half costs muscle fibers you'll need on the run.
• A clear power ceiling: decide before the race the maximum you'll allow yourself on climbs (roughly no more than 105-110% of your target race power) and stick to it.
• Gearing: with 595 m of elevation gain and ramps that aren't extreme, a cassette that lets you spin uphill without torching your quads is a smart choice. The maximum gradient details aren't published in the sources consulted: check the updated elevation profile on the official course page.

The times you can expect

Our rough estimates, not official data: a relaxed finisher wraps up the bike around 3h20, a mid-pack goal sits around 2h55, a fast athlete around 2h35, and top age-groupers under 2h25. Wind can shift these numbers by 10-15 minutes in either direction: race by watts, not by the clock.

What to do now: three concrete actions

1. Test your wind management in training. Find an exposed route and do long intervals at constant power into a headwind. Learn not to react to gusts. 2. Simulate the end of the leg. On your long rides, finish the last 15 km slightly below target power, then run 3-5 km right away at race pace. If your legs won't turn over, your bike target power is too high. 3. Practice the aero position in long blocks. If you can't hold 30-40 continuous minutes on the aerobars, start working on it now: on this course, position is worth as much as watts.

The decision to make

This isn't a course where you "see how it goes." Arrive at the start with a defined target power, a ceiling for the climbs, and the discipline to stick to them even when the group around you is doing something else. Anyone who escapes in the windy sections of the first 45 km, you almost always reel back in along the Turia seafront.
