Race Day at 70.3 Luxembourg: Timeline, Classic Mistakes, and Plan Bs

Two Days Out: Your Homework

With T1 in Schengen and T2 in Remich, pre-race prep is more demanding than average. Use the days before to:

• Recon the bike course, at least the middle section: the hills through the vineyards after the L146 and the descents with sharp corners flagged in a 2018 report should be seen beforehand, not discovered mid-race. Alternatively, study the course on Rouvy.
• Walk both transitions: visualize the swim exit in Schengen, the route through T1, and the entry to T2 in Remich (in 2018 it included ~400 m of running).
• Athlete briefing: with a river swim where one report notes a headcurrent in the first ~700 m, the briefing info on water and current conditions matters more than usual.

The Day Before

Bike check-in in Schengen, bags per the athlete guide procedures. Plan your logistics: two transition zones means twice the time. Golden rule: everything dropped off by early afternoon, then feet up. Prep two swim scenarios: the official average water temperature is 20 °C, but one race source cites 23 °C. Bring both your wetsuit and a swimskin and wait for the official wetsuit call.

Race Morning

Wake up early. In 2018 there was parking with a shuttle bus to transition: if that setup repeats, add 30-45 minutes of buffer to your plan. Once in T1: tires, bottles, nutrition on the bike, then warm up. If possible, get in a few activation strokes: the 2018 report mentions murky water, so better to get your eyes and head used to it before the start.

In the Race: The Three Classic Mistakes

Mistake 1 - Starting the swim too easy. If there's a headcurrent in the first ~700 m like in 2018, a soft start leaves you stuck in the worst spot. Train hard starts and execute one, then settle in.

Mistake 2 - Burning matches in the first 35 km of the bike. The opening stretch along the Moselle is flat and fast, often with a tailwind. In 2018, after the turnaround, 15 km of strong headwind punished anyone who had overcooked it. Watts below target in the first half, always.

Mistake 3 - Running the first run lap at dream pace. 21 km with 5 m of elevation gain over 3 laps: no climb slows you down, no descent gives you recovery. With average highs of 27 °C in July and higher spikes reported, the midday heat is real. First lap under control, hydrate at every aid station, and the third lap will be yours.

Plan Bs

• Water warmer than expected: if wetsuits are banned or not advised, you've got your swimskin ready. No drama: the swim is a single 1,724 m loop.
• Strong wind on the bike: accept lower speeds in the headwind section, hold your power, get lower in your position. The race is decided on the flat run, not your bike average.
• Heat above 30 °C: cut your run target by 10-15 seconds per km from the start, water over your body at every aid station, walk the aid stations if needed. Finishing in control beats blowing up at km 14.
• Mechanical on the cobbles or speed bumps: carry the minimum to fix a flat and check that bottles and storage are tightly secured in the morning.

Afterwards

Finish on the Route du Vin in Remich, near the outdoor pool. Then collect your bike and bags per the procedures: with split transitions, find out in advance where and when to pick everything up. One last tip: if your accommodation sits on one of Remich's steep climbs mentioned in race reports, plan ahead so you're not hauling bike and bags up a ramp after the race.
