I would have to agree with AdamKTM on this one, the beginners ride with TS would work. The mild has a few challenging sections. Tombstone would you so kind to run a Noob route for the guys who want to join?Will mild be fine for someone that just started riding? Also for a mx bike without fans on the radiator?
Quite a bit of time between now and then to make a firm commitment, but for now, no problem
