I’ve done this before and have to echo what the other have said with regards to picking a tyre you’ll be confident climbing and descending grassy and muddy trails. When I’ve done it before the rocks were minimal, no roots I can remember so pick something for greasy condtions you don’t mind pedaling for a few hours 😀 Oh, and it will likely be chilly on top so don’t be tempted to underdress!
Guessing its a big climb, big descent, big climb, big descent etc.
It feels more like “big climb, big climb, big climb, big descent…” good physical challenge with great organisation and a very chilled feel. I really enjoyed it, but sadly can’t ride this year so have a spare entry going if anyone wants it?
