The Marathon: 3 Flat Laps Where No Hill Can Save You
42 km between Calella and Pineda de Mar along the seafront, roughly 50 m of total elevation gain: you set the pace yourself, and that's the problem.
The course
Three laps between Calella and Pineda de Mar, alternating seafront and urban sections. In 2024 the layout was: an introductory 1.6 km stretch through a park, then three 13.5 km laps along the coast. Total elevation gain around 50 m: a few overpasses, gentle gradients, nothing else. The finish is on the beach, with big crowds and a European season-closer atmosphere.
On paper it's the dream of anyone chasing a time. In practice, a flat three-lap marathon is one of the toughest mental tests in long distance triathlon: no climb 'justifies' slowing down, no descent gives you free recovery. If you slow down, it's because you got something wrong earlier.
The real opponent: repetition
Three laps means seeing the same spots three times. In the first 10 km it feels like an advantage: crowds, landmarks, familiar aid stations. From the second lap on it becomes a test of discipline. Prepare mentally: break the race into segments (aid station to aid station, not lap to lap) and give each segment a concrete job — drink, take a gel, check your form.
Another consequence of the laps: on the road you'll always have athletes faster and slower than you. Don't latch onto anyone's pace. Run your own race with your own number.
Aid stations: what you'll find
Aid stations roughly every 2.5 km with water, diluted electrolyte drink served in cups, Maurten gels (with and without caffeine), bananas, oranges and salty snacks. Two decisions to make before race day:
- Course nutrition or your own? If you plan to use the Maurten gels, test them now in training at race pace. If your stomach doesn't like them, plan how to carry your own (special needs, gel holder, trisuit pockets).
- How will you drink from cups? Walking for 10 seconds at an aid station costs less than a hydration crisis at km 32, especially in the afternoon.
Afternoon heat
In early October average highs are around 25°C, with peaks up to 27°C. If your marathon falls between noon and 5 pm, you'll be running the hottest hours on a seafront. It's not the extreme heat of other races, but for an athlete running 4-5 hours it matters: steady hydration from the first aid station, ice or water over your body if available, a cap. Don't wait until you're thirsty.
Pacing by goal
Rough estimates: a happy finisher closes the marathon around 5:00, a sub 12 around 4:20, a sub 10:30 around 3:45, a top age-grouper going sub 9:30 around 3:20. The flat-course rule: the pace for the first 10 km should feel ridiculously easy. On this course the classic mistake is leaving T2 at half marathon pace because the legs are turning over and the road offers no resistance.
What to do now
Three concrete actions:
1. Test the Maurten gels (or decide to carry your own) in your upcoming long runs. 2. Train race pace on flat, monotonous routes: a seafront, a bike path, anything that simulates the lack of stimulation. Learn to hold pace when your brain gets bored. 3. Write your segmented plan: target pace for 0-10 km, 10-30 km, 30-42 km, with the first block deliberately held back. Calella's flat marathon rewards those who start slow. The wall at km 30 isn't built by the course: you build it yourself in the first 90 minutes.
