The 70.3 Nice Run Course: Flat, Fast and Not a Metre of Shade

The Course: Two Laps Along the Seafront

The run is two laps along the Promenade des Anglais: 21.1 km (20.9 km according to the official page) with a stated 119 m of elevation gain. In practice, it's flat. Tarmac, seafront, finish on the Promenade itself. After a bike leg with 1,248 m of climbing and the Col de Vence, it's the right course for athletes who know how to pace themselves: you can run fast here, if your legs are still intact.

The Real Opponent Is the Sun

The course is completely exposed, with no shade, right along the sea. Official data shows highs around 26 °C in mid-September; a local source cites lower highs, around 22-23 °C. The sources disagree, so prepare for the worst-case scenario: two hours or more of running under the sun on heat-reflecting tarmac. A cooling plan is not optional: cap, sunscreen already in T2, water over your head at every aid station, ice if available. Anyone who's raced a summer half marathon knows the difference between managing the heat and suffering it is worth whole minutes on the second lap.

Aid Stations: Every 1.8 km, Familiar Products

Aid stations are positioned every 1.8 km: over two laps that means frequent passes and no need to carry big supplies. On course you'll find Maurten gels, Maurten Solid 160 and Precision Fuel PH 1000. Two options: either test these products in training in the weeks beforehand, or carry your own in a race belt or trisuit pockets. The third option, improvising on race day, is the one that fills the stories of blow-ups at kilometre fifteen. No aggressive fuelling advice here: simply, don't try anything new on race day.

Pacing: Your Half Marathon Is Decided on the Col de Vence

It sounds like a paradox, but the pace of your run is set on the climb, three hours earlier. If you arrive in T2 with burnt legs, the flat course won't save you. Rough projections (estimates, not official data) range from 2:25 for the relaxed finisher to 1:30 for the top age-grouper, passing through 2:05 and 1:48 at intermediate levels. The two-lap format helps with pacing: controlled first lap, a touch below goal pace, then decide at the turnaround whether you have room to negative split. On flat terrain the risk is always the same: going out at your open half marathon pace, which doesn't exist here.

What to Do Between Now and Race Day

• Add brick runs after long rides with climbing: it's the specific combination this race demands.
• Test the on-course products (Maurten gels and Solid, Precision PH 1000) on at least two long runs, or decide what you'll carry yourself.
• Train your run in the hot hours at least a few times, to get used to managing water and cooling.
• Prep your T2 routine: sunscreen, cap, any salt tabs or gels in your race belt.
• Set your first-lap pace before the race, not during it: write it down and stick to it. The second lap will tell you if you were right.

One last practical note: the finish is on the Promenade, in the busiest part of the seafront. With two laps, your family sees you pass multiple times without moving: it's worth agreeing on a fixed spot to look for them, because in the final stretches a familiar face is worth as much as an aid station.
