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

A fast race is won in the details of the days before. In Erkner the course won't challenge you technically: the real traps are the crowded lake start, the mid-September morning chill and a few details still to be confirmed. Here's how to plan your week, the day before and race morning, with the typical mistakes and your Plan Bs.

The Week Before

First: double-check the date and official schedule. Sources disagree on September 12, 2027, so the whole plan starts with confirmation from the organizers. Second: a real taper, with a couple of short race-pace efforts. Third: watch the forecast from five days out; in mid-September air temps run roughly 10 to 20 °C, and the difference between a 10 °C morning and an 18 °C one changes your clothing and warm-up.

The Day Before

Bib pickup and briefing: listen above all for confirmation on water temperature, wetsuit rules and the number of run laps, because current sources don't agree (3 or 4 laps). If bike check-in is the day before — times to be verified in the athlete guide — bring it with gearing and setup already final. If you can, ride a short section of the bike course to assess the tarmac and wind, and look at the lake from the Strandbad: flat, wooded shores, generally calm lake water. Eat dinner early, with foods you've tested.

Race Morning

Wake up about three hours before the start, eat your tried-and-true breakfast, arrive at transition with time to spare. Short checklist: pump the tires, mount your nutrition, check your gearing, position your shoes. Dress in layers: at 10–12 °C at dawn, a light throwaway layer you hand off to family keeps you from burning energy on the cold. The wetsuit is likely, with water reported around 20 °C by a third-party source, but the final call comes at the briefing or on race morning itself: bring everything you need for both scenarios.

In the water: the start is the most chaotic moment. Pick a position that matches your level, start controlled and find steady feet to draft: on a single 1.9 km lap in calm water, drafting is free seconds.

Common Mistakes on This Course

• Going out hard in the swim to escape the pack and arriving at T1 already in the red
• Getting dragged along by the speed in the first 30 km of the bike: on flat terrain your average climbs easily and the bill comes due on the half marathon
• Underestimating the wind: ride to power, not speed
• Not knowing how many laps the run has: confirm it at the briefing and decide how you'll count them
• Overdressing or underdressing for a cool September morning

Plan B

Wetsuit-optional or banned scenario: unlikely at around 20 °C, but be mentally ready for both options and bring clear and tinted goggles to choose based on the light. Strong wind scenario: drop your power target by a few watts in exposed sections and recover in sheltered ones; the race is decided on the run. Rain scenario: fresh tarmac and a non-technical course help, but drop your tire pressure slightly and brake earlier in the few corners. Rescheduled date scenario: if you booked cancellable accommodation, as suggested, you lose little or nothing.

Rough Timeline

• Two days before: arrival, bike assembly, easy shakeout ride
• Day before: bib, briefing, bike check-in if required, course recon, early dinner
• Morning: wake up -3h, breakfast, transition, warm-up, start
• After the finish: collect bike and bags during the times set by the organizers
