here’s my video showing you the route https://youtu.be/i-QbeVVxyEQ
its a mostly for course going through the villages of Weston Turville, Wendover & Halton.
The Halton section has some uphill but it’s not horrendous & there’s downhill afterwards going back toward Some Weston Turville so it balances out
well organised, really affordable at about £12 but no medal at the end, it was a buff instead so I guess you’re getting what you pay for there.
