Challenge Intro: A long day! Get those legs ready for an endurance mixed surface challenge. We will post files and segments a week or so before the event.

  • Timed segments with various categories and awards.
  • Semi Supported: a van will follow riders providing cold drinks, snacks and access to the riders small bag.
    Otherwise its self-supported. If you’re unable to get around the course then we can arrange van pickup at extra cost.

Please understand these rides are not professional races but small scale amateur cycling challenges. To maximize social fun and minimize stupid behaviour 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. Sunday will be a social ride.
