Race Day: Timeline, Common Mistakes, and Plan Bs

The Days Before: The Race Is Won Here

Arriving in Calella with margin is half the job. In the pre-race days you have three non-negotiable appointments: village registration, the briefing, and bike and bag check-in. The sources consulted don't list the official 2027 times: verify them in the athlete guide as soon as it's out and build your schedule around them.

Must-dos before check-in:

• Full mechanical check of your bike after reassembly. A 2024 report flags loose cockpit bolts post-assembly: recheck every bolt or see a mechanic.
• Practice swim in the Mediterranean: water is typically clear and flat, average temperature 22°C (24°C in 2025, 21.5-22°C in 2024). Test the wetsuit you'll race in. The organizers recommend bringing one, ideally with a spare.
• Recon of transition at Camp de Mar: it's big, and in 2024 there were T1 splits of 15:00 and T2 splits of 11:27. Physically walk every route: water→bag→bike→exit, and bike-in→run bag→run out.

Race Morning

Early October in Calella: around 16°C at wake-up, with highs climbing to 25-27°C. That means two things: dress in layers for the wait on the beach (an old throwaway hoodie works) and decide in advance how you'll handle the cool start on the bike — arm warmers or a light gilet to shed as the sun comes up.

If you're staying in Calella within 3 km of transition, you can reach everything on foot: no shuttles, no traffic. It's one of this race's big advantages: use it to sleep 30 extra minutes, not to show up at the last second.

In transition: pump your tires, mount your bottles, check the bike shifts. Then wetsuit on and head to the beach. The start is from Calella beach, a single 3.8 km lap with two very long straights (1,250 m and 1,550 m): pick out your sighting landmarks from shore before the start, because buoys will be few and far apart.

The Day, Leg by Leg

Swim: the sea is typically flat and crystal clear; some reports mention a few jellyfish, not a systematic problem. The real risk is swimming crooked on the long straights: sight at regular intervals.

T1: big transition zone. Don't run in a panic: move with purpose but precision. Transition minutes in Calella are inherently long; budgeting for them stops you from trying to 'claw them back' by pushing too hard in the first 20 km of the bike.

Bike: 2 laps toward Badalona, 750 m official elevation (774 on the course page, 1,000+ on athletes' GPS files). Steady watts, aero position, two 5% climbs per lap to spin up smoothly. Eat and drink from the start: the flat course invites you to forget.

Marathon: 3 flat laps between Calella and Pineda de Mar, aid stations every 2.5 km with water, electrolytes, Maurten gels, fruit, and salty snacks. The afternoon can hit 25-27°C: cool down and drink at every aid station. Start slower than you want to.

Finish: on the beach, with the crowd of the European season closer. Enjoy it.

The 5 Common Mistakes

1. Underestimating transitions: 20+ minutes total is realistic here. Plan for it. 2. Trusting the official 'flat' on the bike: false flats exist, the GPS files confirm it. 3. Starting the marathon hot because the course offers no resistance. 4. Not testing the aid station products (Maurten gels, electrolyte drink in cups) before race day. 5. Commuting from Barcelona on race morning.

Plan Bs

• Wetsuit: the final call comes on race day; with an average of 22°C it's almost certainly wetsuit-legal, but bring a spare as the organizers themselves suggest, and mentally prepare for a non-wetsuit scenario too.
• Mechanical: complete, tested flat kit.
• Afternoon heat: if the run goes bad, switch to the 'finisher' plan: walk the aid stations, drink, get there. The beach finish is worth it even at a slow pace.
