The Kraichgau Bike Course: 90 km of Hills That Punish Anyone Who Goes Out Hard
Over 1,000 m of climbing, steep ramps through forests and vineyards, and an intermediate cut-off at km 34: here's how to tackle the leg that decides the race.
The Big Picture
A single loop of roughly 88-90 km with 1,029 m of official elevation gain. Athletes' GPS units have recorded as much as 1,100-1,200 m: the difference doesn't change the story. This is not a PB course. Race reports describe it as very hilly and technical, with steep ramps cutting through the forests and vineyards of the Kraichgau. If you show up expecting a fast, free-flowing bike leg with a high average speed, you've picked the wrong race.
How the Loop Unfolds
The first 10 km are fairly flat. It's the classic trap: fresh legs after the swim, adrenaline, groups hammering. After about 20 minutes the hills start and they don't let up until T2. There's no signature 20-minute climb: it's constant up and down, with punchy ramps where the wrong gear costs you immediately. The technical nature of the course demands attention on the descents and in the pace changes too: every surge burns watts you'll need later.
Pacing: Keep Something in Reserve
The rule is simple: what you save in the first 10 km, you get back at km 70. On the short ramps, avoid power spikes well above your threshold: on a course with dozens of kickers, repeated spikes drain your legs more than one long, steady climb. Ride the climbs at your middle-distance pace, use the descents to recover and eat, and remember there's a half marathon afterward that in 2018 and 2019 was run in 30 °C and above.
Gearing and Bike Choice
With over 1,000 m of climbing in 90 km and steep ramps, gearing is a decision, not a detail. A compact (50/34) with a wide cassette (11-32 or bigger) is the safe choice for most age-groupers. Concrete test: if you can't hold a cadence above 70-75 rpm on the ramps in training with your easiest gear, swap the cassette. A TT bike still makes sense because there are plenty of rideable sections, but set it up so you can stay seated on the kickers.
Cut-offs and Rules to Know
Two numbers to memorize: you must pass the Luisenhof roundabout at km 34 by 12:00, and swim+T1+bike must be done within 5h30 (rules listed for the 2026 edition: check for updates for 2027). If you're a back-of-the-pack athlete, work out your splits in advance and make sure you have a buffer. Watch out for drafting: there's a penalty box at the entrance to T2 as well, so the rules apply right down to the last meter of the race.
Specific Training
Three things to put on the schedule. First: hill repeats, blocks of 1-3 minute surges with rolling recovery, to get your legs used to the sawtooth profile. Second: long rides on rolling terrain with constant power control. Third: brick sessions with a hilly ride followed by a run at race pace, because that's where this course sends the bill.
The Unexpected
One athlete in 2019 reported a wasp sting on the bike: if you're allergic, carry your medication with you; there are Red Cross stations along the course. On wind, the sources offer no reliable data: the index is neutral due to lack of information, so don't build a strategy around it.
What to Do Now
Decide your gearing and test it on a course with repeated kickers, not on the flat. Set your power ceiling for the climbs and stick to it in at least two long simulations. If your target is around a 3h30-3h45 bike split, calculate your expected arrival at km 34 and check your margin against 12:00 before you get to the start line.
