Bikepacking race — solo / pairs
Difficulty
Savage

One of the steepest short-format bikepacking races in the UK. A self-supported loop from Hebden Bridge through the Calder Valley gritstone, roughly 151km or 235km. Dot-watched, no support, no prizes.

The valley shape means you are almost always climbing or descending steeply, on brutal gritstone bridleways, cobbled packhorse causeways and boggy moor. Around 4,000m of climbing on the short route, 6,500m plus on the long.

Do not let the modest distance fool you. The climbing-per-km is among the highest of any UK bikepacking event, and hike-a-bike on the steepest cobbles is guaranteed. Short, not easy.

Who this suits

Is Calder Divide Trail for you?

  • Strong climbers who accept walking. Even on fresh legs, the steepest gritstone and cobbles force everyone off the bike, so pushing is part of the plan, not a failure.
  • Riders who dial in a low gear and grind. Under-gearing wrecks the legs on these gradients; the right ratio is the single best decision you make.
  • Self-sufficient types happy navigating solo by GPX with no course markings, carrying enough for the service-free moor loops.
  • Anyone who reads short and still respects it. The relentless up-and-down grinds harder than the distance ever suggests.
Training plan

Training plan for Calder Divide Trail

A training plan for Calder Divide Trail isn't a generic base build. Beina reads the event's exact demands, looks at your specific profile and the time you actually have, and maps a highly adapted plan to the start line.

01 · Race demands
What the Calder throws at you
  • Relentless steep climbing: roughly 4,000m to 6,500m plus packed into a short loop, with almost no flat to recover on.
  • Hike-a-bike guaranteed. The steepest gritstone and cobbled causeways force even strong riders to push.
  • Technical handling on wet gritstone, jarring cobbles and boggy moor tops that catch Pennine weather.
  • Self-supported navigation by GPX, with a possible night out on the longer route.
02 · Key sessions
What your weeks look like
  • Long hilly endurance rides, 4 to 7 hours off-road, chasing 1,500 to 2,500m of climbing rather than flat miles.
  • Steep-terrain rides on 15 percent plus gradients, plus deliberate loaded hike-a-bike practice.
  • Hill repeats, 5 to 8 x 4 to 5 minutes on a steep gradient, backed by lower-body gym work.
  • Weekend doubles on tired legs, and a night ride for navigation confidence if you choose the long route.
03 · Shaped around you
Not a generic schedule
  • Built from your current fitness and the time you actually have
