What the course asks of you
The mountain passes of Gangwon province are long and often steep, linked by valley roads; the hors-catégorie climb is the hardest effort of the day. With 208 km and five big climbs, it is a full mountain day.
The 12-hour limit leaves room, but only for riders who pace the first climbs. Train long climbs at a steady effort and eat on a schedule from the start.
How to prepare
The general shape of a good preparation, which Event Coach turns into a plan for your fitness, time and date:
- Train long climbs: steady efforts of 30 to 60 minutes just below your threshold match the cols of the Seorak Granfondo far better than short intervals.
- Build the long day: rides of five to seven hours in the final two months, towards the 208 km of the route you choose.
- Practise eating and drinking on a schedule, and descending: a mountain day is as much going down as going up.
Pacing mistakes to avoid
The mistakes that cost riders the most on a day like this:
- Treating the first climb of the Seorak Granfondo as a race: a long col ridden above the pace you can hold for hours costs you the rest of the day.
- Saving nothing for the last climb, where the most kilometres are already in your legs.
- Skipping food on the descents: the next climb starts with what you ate on the way down.
