The Rift: Training Guide
A 200 km loop of the Hekla volcano — black sand, glacial rivers, and relentless Icelandic wind.
The Rift is a gravel race set in the volcanic landscape of southern Iceland, looping around the Hekla volcano on roughly 200 km of gravel, black sand, and lava rock, with a shorter option also offered. It crosses several unbridged glacial rivers and runs through wide, open terrain with almost no shelter — a genuinely wild day that has earned a cult reputation among gravel riders.
There is no big mountain pass to conquer here. The difficulty comes from the surface, the river crossings, and above all the wind: long stretches of exposed, sapping terrain where conditions, not gradient, decide how hard the day becomes.
What makes it hard
- Wind and exposure. The open volcanic plains offer no shelter, and Icelandic wind can turn a flat section into a grinding effort — it is often the single biggest factor in the day.
- Loose black sand and lava rock. Soft, sapping surfaces cost real energy and demand relaxed handling to carry momentum instead of fighting them.
- Glacial river crossings. Cold, fast water and uncertain footing mean you may dismount and wade; it is slow, chilling, and unlike anything most riders have trained for.
- Remote self-sufficiency. The landscape is wild and weather changes fast, so you carry your own food, layers, and the ability to look after yourself between aid points.
What the day actually demands
The Rift is an aerobic-endurance race where the limiter is rarely your climbing power — it is your ability to hold a steady, efficient effort over many hours on a draining surface and into the wind. Riding in a group to share the wind, staying smooth through sand and rock, and keeping your effort controlled all matter more than top-end power.
Train the all-day engine and the mental patience to keep an even effort when the wind and surface are conspiring against you. Panicking and surging in the soft stuff or into a headwind is how riders blow up here.
How to build toward it
Build 12 to 16 weeks of endurance, with the long ride as the centrepiece, growing toward the many hours the 200 km will take at your pace. Add tempo and sweet-spot work so a long moderate effort is repeatable, and — if you can — deliberately train in wind and on soft or loose surfaces to rehearse the specific demands.
Practise riding loaded and self-sufficient, and get comfortable with the idea of dismounting for river crossings: how you will protect your feet, manage the cold, and remount and keep moving without losing your rhythm or your core temperature.
Fueling and cold-water habits
Aim for 60–90 grams of carbohydrate per hour and keep eating steadily, even when wind and cold suppress your appetite. Plan to be self-sufficient between aid points, and respect how much the river crossings and exposure can chill you — staying fuelled and warm enough to keep producing power is as much a part of the challenge as the riding itself.
Equipment and conditions
Riders typically choose tyres with enough volume and grip to stay confident in soft black sand and over lava rock, and pack windproof, waterproof layers for fast-changing weather even in July. Because the terrain and crossings are unlike most gravel races, check the official site for the current route, river-crossing guidance, and mandatory-kit requirements before you go.

Common questions
How hard is The Rift in Iceland?
It is a serious 200 km gravel day — but the difficulty is the surface, the glacial river crossings, and especially the wind and exposure rather than big climbs. Conditions vary enormously year to year, so the same course can feel very different depending on the weather. A shorter route option makes it more approachable.
Do you really have to cross rivers at The Rift?
Yes — the course includes unbridged glacial river crossings, and depending on water levels you may dismount and wade. They are cold and can be slow, so it is worth planning how you will keep your feet and core warm and get moving again afterward. Check the official site for current crossing guidance and any mandatory kit.
How do I train for the wind and black sand?
Build a deep endurance base, then practise holding a steady, controlled effort into headwinds and over soft or loose surfaces. Learning to stay relaxed and carry momentum through sand — rather than fighting it — and to ride efficiently in a group to share the wind will save more energy than any amount of extra top-end power.
