Race Intelligence · Erkner, Germany
Erkner's lakes and flat roads can make a 70.3 look like a gift to the time-trial specialist. The trap is riding as though the course owes you a fast run too. It doesn't.

Your day in Erkner
I’m Tom, the coach behind Sense Endurance Coaching. Tell me where you are now and I’ll show you what a strong day in Erkner could look like.
The course behind your race
The 2026 race began with a rolling start in Dämeritzsee, followed by two flat bike laps near the Spree and Neu Zittau and a run through lakeside and Rathauspark. The 2027 date and course still need confirmation before you build travel or pacing around them.
Strandbad Erkner, previous rolling swim start
Flat wooded banks and clean, clear water at Strandbad Erkner give a genuinely low-drama opening. Settle into rhythm rather than racing a swim that offers nothing to fight.
Settle by 300 m. Hold a controlled, repeatable effort.
Dämeritzsee, later swim course
Newly paved, flat roads along the River Spree make this course genuinely fast, and genuinely easy to over-ride. Set the power number you can hold for two full loops.
Cap power in the first 15 minutes. Fuel early on the smooth roads.
Spree-side roads, first bike circuit
As the first loop closes back through the Brandenburg countryside, hold the discipline you'll need for an identical second loop.
Stay on the fuelling schedule. Keep power consistent through the closing kilometres.
Neu Zittau direction, middle bike stage
The second loop repeats the same flat, fast terrain. Ride to the same power ceiling, especially through the sections that felt easy the first time.
Compare effort to loop one. Finish planned nutrition before T2.
Hartmannsdorf and return, previous route
The run passes Erkner's beautiful marketplace and the Gerhart-Hauptmann-Museum with strong local support. Nothing here should feel hard yet.
Shorten stride out of T2. Hold opening pace regardless of the crowd.
Rathauspark, opening run stage
Passing the same marketplace and museum a second time gives a clear read on how loop one's pace is actually holding.
Compare loop two to loop one. Keep aid-station fuelling on schedule.
Dämeritzsee run corridor, later section
This is where a hard-ridden bike, even on flat terrain, starts to show up in the legs. Manage the effort you actually have.
Reassess goal pace honestly. Keep taking aid on schedule.
Erkner sports-centre approach, final run
The final loop finishes among Erkner's strongest crowd support. If the bike was paced evenly across both loops, this is where it pays off.
Decide the finish honestly. Save something for the final loop.
Confirm the reported September 2027 date from IRONMAN and acquire the current Dämeritzsee swim, flat bike laps and town run map. The 2026 5150 and 70.3 share nearby event information; do not copy the sprint-distance route into this half-distance dossier. Check transition and local traffic arrangements plus aid and start waves.

Prepare for Erkner
A finish range gives you something to work towards. The preparation is specific to this race: an honest lake opening and patient flat-road watts feed a controlled repeated town run rather than an overambitious bike personal best.
I’m Tom. With Sense Endurance Coaching, I’ll build that preparation around your life, follow how you respond and adjust the work as you get closer to Erkner.
