The Kalmar Bike Course: 180 Fast Kilometers, but the Öland Bridge Calls the Shots

The big picture

180 km with minimal elevation gain. Sources quote figures between roughly 300 and 500 m of climbing: either way, not much. There are no real climbs. This is a course for steady power, aero position, and discipline. The signature stretch is the Öland Bridge: about 6 km suspended over the strait, exposed to the Baltic wind. You head out of Kalmar, cross the bridge, loop around the island of Öland, and come back to the mainland.

Heads up: sources don't agree on the exact course layout. Some describe a single loop, others two separate sections of roughly 122 and 58 km. The official 2027 map is the only valid reference: check it before planning your pacing and aid stations.

Wind is variable number one

On the bridge and along Öland's open stretches, crosswinds and headwinds can make average power pretty meaningless. Several race reports and course analyses point to wind as the deciding factor here, more than elevation. What that means in practice:

• Don't chase speed. Into a headwind you'll go slow even at full watts. With a tailwind you'll fly almost for free. Set a power target (or RPE target) and hold it.
• Don't try to claw back lost minutes. If the bridge costs you time on the way out, accept it. Pushing above threshold to "make it back" gets paid for on the marathon.
• Crosswind on the bridge: hands near the brakes if gusts are strong, especially with deep-section wheels. Pick your wheel depth based on race-day weather.

How to prepare

Three key sessions in the months beforehand:

1. Long rides in aero position. The goal is holding position for 5-6 hours without your back and neck giving out. Progressively increase continuous time on the aerobars. 2. Steady pedaling. Fixed-power workouts on flat routes, even in boring conditions. The winner here is whoever avoids power dropouts, not whoever hits the spikes. 3. Crosswind handling. Seek out windy days and get used to the bike moving underneath you. Safety on the bridge is worth more than a few watts.

Equipment and gearing

For this course a TT bike, or at least clip-on aerobars, is the obvious choice. The elevation doesn't justify compromising on aerodynamics. On gearing: you don't need climbing gears, but an easy gear helps in strong headwind sections, where cadence tends to collapse. Decide your wheel depth only after the final days' forecast: in strong gusts, a mid-depth front wheel is more manageable than a full disc setup for anyone not used to it.

Your race plan

• Before the race: download the official 2027 map and study where the exposed sections and aid stations are. Descriptions from past editions are indicative only.
• Pacing: set a power ceiling and a working range. Write them on your handlebars if you need to.
• On the bridge: controlled effort, clean lines, watch out for other athletes getting pushed around by gusts.
• On Öland: it's the longest and most exposed part. Eat and drink here regularly, even if the wind makes taking your hands off awkward.
• Heading back to Kalmar: resist the urge to finish strong. The last 20 km ridden easy are worth 10-15 minutes on the marathon.

The verdict: an honest, fast course for anyone who shows up ready to ride steady in the wind. Treat Kalmar like a sheltered time trial, though, and you'll find out halfway through the marathon.
