My lessons from my first attempt last year….
Be comfortable on your bike…whatever that means to you. Lots of recommendations that work for one will not for another
Mentally. Be ready….. It is exciting adrenaline filled at times…but….there are bleak moments….cold fell well actually before for me as it was all rolling and sapped my energy as I was alone for most of it
Make sure your bike works and you can repair it…..iwas amazed at all the breakdowns especially by pimped out carbon Raphael wearing men who could not repair their bikes
It is okay to walk….yeah fine do not listen to or be fooled into machismo
Training…. Cycle wise miles is good but spinning will help personally cross training will be helpful so running and I would say core strength…the climbs are big but it is the totally affect on the body.
Oh eat…real food…..gels and power bars are okay but I saw lots of people’s bodies reboot in explosive ways…
Remember it is a ride not a race….
