The original Grinduro: a gravel/enduro hybrid + party. A ~75km gravel loop where only ~3–5 timed segments decide the result and the rest is ridden at your own pace. Isle of Arran / Scottish venue. Date and figures approximate (est. summer 2027).
Location
Isle of Arran / Scottish venue (varies)
The original Grinduro, and the format is the whole story. You ride a big ~75km gravel loop, but the clock only runs on a handful of marked segments. The sum of those decides your result.
Around 1,800m of climbing over gravel roads, forest and estate tracks, on an Isle of Arran or Scottish venue that varies year to year. Between the timed stages you ride at your own pace: social, unhurried, well fed.
So a big steady engine will not win this. The result comes from short, committed punch on the timed climbs and nerve on the technical descents. Then the party, because that is half the point.
Who this suits
- Punchy riders who recover fast. The result is a few short, near-max efforts with easy transfers between, so a sharp engine beats a steady diesel.
- Confident descenders. The timed descents hand free time to riders who commit on loose, often greasy Scottish gravel.
- Anyone with the base to complete a hilly 75km. That is the entry ticket, and you ride most of the loop at your own pace.
- Riders who want the race and the party. Grinduro is a social day as much as a result, and it rewards treating it that way.
Training plan
A training plan for Grinduro Scotland 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
Punch and skill, not a steady grind
- Only three to five timed segments decide your result; the rest of the loop is untimed and social
- Short, near-max efforts on the timed climbs, with recovery in between
- Technical descents on loose, often wet Scottish gravel, where handling is free time
- Enough endurance to complete ~75km and 1,800m of climbing comfortably
02 · Key sessions
What your weeks look like
- Short Hard Repeats: 6 to 10 by 2 to 5 min near-max with full recovery, for timed-climb punch
- VO2 intervals: 5 by 3 min to raise your ceiling for the segments
- Grinduro simulation: a 3 to 4 hr easy loop with 3 to 5 all-out segments, full recovery between
- Dedicated descending and gravel-skills sessions on loose, wet lines
03 · Shaped around you
Not a generic schedule
- Built from your current fitness and the time you actually have
- Adapts every week as Beina learns how you respond
- Syncs your sessions straight to Garmin and Wahoo
- One clear next session, never a wall of spreadsheet
