I would love to be out there, not racing it, but doing a supported tour of the best parts.... 40 to 50 miles a day would be lovely without the abuse and risk of falling apart physically. More a stop and smell the flowers tour, not race. Being old and slow has it's limits. But I for sure would build a hard tail, most likely geared 3 x 9 29'er.
Adventure Cycling....fully supported tour....this month.
