A great idea for a thread. I'm 69 semi retired working 20 hrs a week. I have a Wabi Lightning scandium frame built with good track quality components. Do a lot of longer road rides through rollers. Saturday I rode 3.5 hrs and yesterday 3 hrs on the Wabi and the previous Saturday 4 hrs. I'll build up endurance and do a century before it gets hot. I also have a Lynskey Helix Ti road bike and a Hans Schneider custom steel road bike. I'm trying to ride 10-12 hrs a week with intervals once a week and either a hard (for me) group ride, usually on a geared bike, or a long solo fixed gear ride on Saturday. I've been riding about 25 years and raced 10 years from the mid 80s to mid 90s. Was off the bike 8-9 years getting fat and started again in 2004. I've been riding fixed gear about 3 years. I find I need more recovery. On a consistent basis I can only do two hard rides a week or I dig a hole and I think it takes three hard rides a week to ride well-the price of getting older at least for me. Loosing weight is hard and putting it on far too easy I carrying 7-8 lbs more of me than I need to get up the hills.
