A long day! Get those legs ready for an endurance challenge. We will post files and segments a week or so before the event to a wechat group setup for this challenge.

Mostly rough road, a bit of offroad, a small downhill walk.

Please understand these rides are not professional races but small scale amateur cycling challenges. To maximize social fun and safety points are given for various challenging segments. The rest of the day is meant to be spent riding and chatting in groups. Cool refreshments provided on-route along with a few fun awards. Please be realistic, these are not aimed at the beginner and are demanding, in amazing but challenging landscapes.

If we have serious weather or health warnings it will be delayed.

GPS & Route

These are not final but are close, from last year for your reference. Final files will be posted to the challenge wechat group a day before the ride. A waterproof printout of the route will also be provided.


Segments will be posted to the wechat group before the ride so you can star them. They are also provided in the GPX / Fit / GPS files.
