Calvin Woodward has tips about such an odessey, which would last at least 3 months he said. For me, it takes a week of recovery from biking 100 mi on a weekend, yet many can pull those distances every day. Astonishing, really. Perhaps if my bike fit me better. As fitness levels increase, biking 60 miles is not a big deal. Currently my problem is 80+ miles, and few people will push beyond 80 miles in one day. I remember one lady from a local bike club who did a double century (200 mi) in one day, which took her pretty much the whole day. Absolutely amazing stamina.
