The Lanzarote marathon: flat on paper, brutal on the body

After 180 km of wind and climbing, the Lanzarote marathon looks like a gift: flat, by the sea, with constant crowd support. Don't be fooled. This is where the bill from the bike and the heat gets presented, and anyone who got their pacing or hydration wrong finds out on lap two.

The course: three out-and-back laps

You run along the Puerto del Carmen seafront, on a course that's basically pancake flat. The first lap is the longest, reaching out towards Playa Honda and Arrecife; the following laps turn around earlier. Three passes over the same stretch mean two things:

• You always see people: constant support, other athletes, your family every 30-40 minutes. Psychologically it's one of the most manageable marathons on the circuit.
• No surprises: after lap one you know every metre. Use that to plan where to slow down at aid stations and where to push on.

Aid stations come every 2-3 km. That's a high density, and you should use it: at Lanzarote, skipping an aid station to save 20 seconds is the fastest way to lose twenty minutes later.

The enemy: dry heat and zero shade

Air temps between 22 and 30 °C, strong sun, almost no shade. Lanzarote's heat is dry: sweat evaporates instantly and the sensation of heat stress lags behind your actual dehydration. The race guides hammer this point: active cooling is not optional.

A concrete strategy, to test in training and not improvise on race day:

• Ice at every aid station: in your cap, in your trisuit, in your hands.
• Water on your body, not just in your mouth: head, back of the neck, thighs.
• Light-coloured cap and sunglasses: the glare off the sea and the tarmac is constant.
• Sodium: with sweat evaporating instantly, it's easy to underestimate how much you're losing.

Pacing by goal

The benchmarks from the race sheet: a 5:10 marathon for a comfortable finisher (14:20 overall), 4:10 for sub 12, 3:50 for sub 11, 3:25 if you're chasing a slot. Note the pattern: at Lanzarote run splits are slower than elsewhere for the same athlete, because you come off the bike more drained and you run in the heat.

Practical rule: run the first 10 km at goal pace plus 10-15 seconds per kilometre, not at goal pace. If you feel good at km 25, you have plenty of time to make it back. If you start at fresh-legs target pace, the wall arrives earlier and hits harder.

The finish: sunset and midnight

Many finish at sunset, with the last finisher coming in just before midnight: the overall cutoff is 17 hours. Once the sun drops, conditions improve noticeably: if you're struggling during the hot hours, the goal is to arrive alive at 7pm, not brilliant at 4pm. Plenty of race reports describe second laps in survival mode and third laps as a rebirth, precisely because of the drop in temperature.

What to do between now and May

1. At least three long runs in the heat before the race: during the hottest hours of the day, with your full cooling strategy. 2. Test ice in training: where you put it, how long it lasts, how your stomach handles cold water under load. 3. Simulate degraded pace: a long run with the first 10 km held back and the finish on feel teaches you the patience this race demands. 4. A written plan B: if goal pace doesn't hold on lap one, what's the survival pace that still gets you to the finish line? Deciding beforehand is easy, deciding at km 28 is not.
