hello everybody

Coming up to 49 years old and am planning on doing the Marmotte next year. (brutal bike ride through the French Alps for the baffled)
I've got just under a year to get down to about 75 kg so have a fair bit to do. (about 15kg) should definitely be doable don't you think?
Anyway, good luck to everybody else that has had a moment of clarity in their life and have got on the path to a healthier lifestyle.
