Tallinn compresses the 70.3 weekend better than most capitals: airport, race centre, Old Town, and the official partner-hotel area sit within roughly 10 km. IRONMAN lists a flat bike and run, with typical temperatures around 10 to 19 degrees. The 2027 edition is confirmed for August 29, with general registration opening August 27, 2026 and pricing still to come. We'd use the city centre as the base and respect Baltic wind more than the elevation chart suggests.

Why we'd pick it
- The 250 m climbing estimate is useful for planning, not a verified pacing number.
- Open · Direct entry — no lottery to lose.
- A non-racing partner gets a real weekend here — 4/5.
- Race day usually sits 12.3–18.5°C, about 47% chance of rain.
The course
The official race page lists a 1.9 km swim, flat 90 km bike, and flat 21.1 km run. That makes Tallinn a strong first 70.3 or a late-summer time target, but Baltic wind can turn an easy-looking profile into a long day. IRONMAN has not published a reliable total elevation figure on the race page, so the 250 m planning number here remains deliberately marked uncertain.
