Race Day in Tallinn: Timeline, Common Mistakes, and Plan Bs

The Days Before: The Race Starts at Check-In

With T1 at Stroomi Beach and T2 at Rocca al Mare connected by shuttles (~15 minutes), the day before is no formality. Recommended plan:

• Two days out: registration at the Rocca al Mare HQ, briefing at the Unibet Arena (don't skip it: that's where you get confirmation on the swim venue and wetsuit ruling), optional practice swim.
• Day-before morning: drop off your bike and bike bag at T1 (Stroomi Beach), run bag at T2 (Rocca al Mare). Factor in shuttle times and leave a buffer: day-before lines are real everywhere.
• Day-before afternoon: nothing. Legs up, early dinner, morning bag packed.

Race Morning: Cold and Waiting

Lows hover around 13 °C. Reports mention long waits in the start corrals in past editions. Concrete countermeasures:

• Bring old throwaway clothes to the start: a hoodie, flip-flops, maybe a towel.
• The lake averages 18 °C, with historical lows even colder: a full wetsuit is almost certain, plus a neoprene cap in your bag, to decide on-site.
• In your T1 bag, consider arm warmers or a vest for the first kilometers on the bike: you'll come out wet with air at 15-18 °C.

The Swim Plan B: It's Not Paranoia

This is what sets Tallinn apart. In past editions the swim venue changed at the last minute, between the Baltic and the lake, due to water temperature or algae. In 2019 the sea read 11 °C the day before the race. The current official page lists a single 3,796 m loop in Lake Raku (clear water, sandy bottom), but history says: keep your options open.

What that means in practice:

1. Check the app and official channels right up to race morning: communications have come with some delay in the past. 2. Mentally prepare for two scenarios: single-loop lake swim or a different venue. A venue change also changes T1 logistics. 3. In training, get in cold open-water sessions. If the first stroke at 16-17 °C takes your breath away, that's a problem you can only solve beforehand, not on race day.

The Typical Mistakes, in Order of Frequency

• Going out too hard on the bike: flat, fast course, 635 m of elevation over 179 km. The false flats and coastal wind run up a bill you'll pay on the marathon. Conservative watts on the first loop, always.
• Trusting the packs: drafting enforcement is strict, with referee motos out on course. A penalty here ruins your race more than the wind.
• Not memorizing the run special needs location: it's in a separate area off the course. On the third marathon loop you won't be thinking straight: study it beforehand.
• Underestimating the small end-of-lap climb: it's there both on the bike heading to T2 and on the run coming back toward Rocca al Mare. Small, but repeated.
• Dressing for a summer race: 13-21 °C with wind and roughly a 30% chance of rain based on historical data. One edition saw rain and gusts up to 56 km/h.

After the Finish Line

At the Unibet Arena you'll find changing rooms, hot showers, and a sauna: a rare luxury on the circuit. Pack a full, comfortable change of clothes in your street wear bag, including roomy shoes. A sauna after a full is a finish few events offer.

The Decision to Make Now

Write out your race weekend timeline: bag drop times, shuttles, wake-up, breakfast, corral entry. Then write your swim Plan B. If you get to the morning of August 7 with both on paper, you've already eliminated half of this race's documented surprises.
