IRONMAN 70.3 Kraichgau 2026 at a glance

IRONMAN 70.3 Kraichgau is one of the most popular half-distance races in Germany, and has a reputation as the climber's 70.3 on the European circuit. Around 2,500 athletes race from a purpose-built transition area at the Kraichgausee lake in Bad Schönborn, through rolling wine country in Baden-Württemberg, and back to a three-lap flat run around the lake. It's the kind of course that rewards patient riders and punishes anyone who overcooks the first climb.

Kraichgau has been on the German triathlon calendar for years and is a natural fit for athletes based in or near Heidelberg, Stuttgart and Frankfurt. It's also a smart stepping-stone race: do Kraichgau in early June, then line up for a full distance at IRONMAN Frankfurt or Challenge Roth in July. The hilly bike course in particular is excellent prep for anything with real elevation.

Key facts

The swim — Kraichgausee lake

The swim takes place in Kraichgausee, a contained lake right next to the race start/finish in Bad Schönborn. It's a two-lap course with a short Australian exit between laps, making it an easy swim to spectate. The lake is clean, calm, and fully enclosed — no boats, no current, no chop. Entry is a mass or rolling start depending on the year.

Water temperature in early June sits between 18°C and 22°C, which puts it well inside wetsuit territory for age groupers. It's a comfortable, confidence-building swim — roughly the same difficulty as a typical German lake 70.3 like Hamburg or Rügen. For swim-weak triathletes, Kraichgau is a friendly place to race your first 70.3.

Expected swim times by level:

• Pro: 22-25 minutes
• Strong age grouper: 27-32 minutes
• Mid-pack: 35-42 minutes
• Back-of-pack / swim-weak: 45-55 minutes

The bike — one lap through Kraichgau wine country

This is the part of the race everyone talks about. The 90 km bike course is a single loop through the rolling hills, vineyards and villages of the Kraichgau region between Heidelberg and Heilbronn. You'll ride past Sinsheim (home of the famous Auto & Technik Museum), through Eppingen's half-timbered old town, and over the rollers around Waldangelloch. The road surface is generally good German asphalt with a few rougher village sections.

Elevation is around 900-1,000m over 90 km. There's no single hero climb — it's a constant drumbeat of 1-3 minute punchy rollers, short enough that you can't settle into a rhythm and steep enough that you can't power through them in the big ring. This is why Kraichgau is called the climber's 70.3 in Germany. Pure TT specialists used to flat courses like Barcelona or Rapperswil will lose 10-15 minutes here compared to their usual 70.3 splits.

The good news: the course is scenic, the crowds in the villages are enthusiastic, and the payoff for a well-paced bike is a run that actually feels manageable.

Expected bike splits (intermediate male age grouper, 35-44): 2:45-3:15. Pros are closer to 2:05-2:15.

The run — three laps around the lake

The Kraichgau 70.3 run is a three-lap out-and-back around Kraichgausee, starting and finishing at the main transition area. The course is flat, fully closed to traffic, and partially shaded — a welcome change after the bike. Aid stations are well stocked and appear every 2-3 km.

The three-lap format is excellent for spectators and for pacing: your family can see you six times, and you can lock into a lap pace you can hold. It does get mentally grindy on lap three if you rode the bike too hard, so pace the first half of the bike conservatively and save your legs for the run.

Expected run splits (intermediate male age grouper, 35-44): 1:45-2:15.

• 2026 entry fee is approximately €395-445 depending on how early you register
• Early-bird registration saves around €50 versus last-minute entry
• IRONMAN 70.3 World Championship qualifying slots are allocated by age group on race day

• From Heidelberg, local S-Bahn S3/S4 reaches Bad Schönborn in ~25 minutes
• Bad Schönborn has two stations (Süd and Bad) — race accommodation in town is walking distance to both

Where to stay

• Heidelberg — 25 minutes by car or S-Bahn, the most atmospheric base. Full range of hotels from budget to five-star, great restaurants, and an easy morning drive to race start. This is the default choice for most international athletes
• Bad Schönborn — small selection of hotels and wellness resorts within walking distance of the Kraichgausee. Books out 6+ months ahead. Best option if you want zero commute on race morning
• Sinsheim — on the bike course, mid-range hotels, good for spectators who want to watch the climbs
• Karlsruhe (30 minutes) — budget-friendly big city with plenty of hotel capacity and an ICE station
• IRONMAN publishes an official partner hotel list closer to race day with negotiated rates

Training specific to Kraichgau

Kraichgau rewards three things: bike durability on rollers, controlled pacing on the bike, and a strong first 10 km on the run. If you're preparing for this race, bias your training toward:

• Rolling hill rides — long Z2 rides with 800-1,200m of climbing every week in the 8 weeks before race day. Flat TT rides won't prepare your legs for the constant rollers
• Short, sharp hill repeats — 2-3 minute efforts at FTP, 6-10 reps per session, in the last 6 weeks. Mirrors the energy system demand of the course
• Brick sessions after hilly rides — 3-5 km off a 2-hour rolling ride teaches your legs to run when they're trashed
• Pacing discipline — do a race-pace effort on a similar hilly course and note your average watts. Target 70-75% of FTP on race day, not 80%+
• Open water swims — the lake is friendly but still open water. Get at least 4-6 open water swims in before race day

Kraichgau vs other 70.3s: where does it fit?

Kraichgau sits at the harder, hillier end of the European 70.3 calendar. Here's how it compares to other popular races on the circuit:

Short version: if you want a Personal Best, Barcelona or Hamburg is the better pick. If you're training for a hilly full distance like Challenge Roth or IRONMAN Frankfurt and want a hard tune-up race in the same country, Kraichgau is exactly right. It's also an excellent race to test your climbing fitness without committing to a full mountain race like Nice.
