There are a number of regular inhabitants of this forum that are still racing into their 60's (I'm not one of them!). We ride our tandem 95% of the time and our goals center around distance and climbing. With a combined age >130 it's not easy doing the longer (100K and 100mi) organized rides in Northern California, but I can see a lot of improvement in our climbing just in the 15 months we've had the tandem (we hadn't bicycled for 20 years up 'til August of 2008). So on the tandem a hilly 100K (4000+' of climbing) at 15 mph is within our reach and I'd like to see us do the same for a hilly century. I do sometimes take my single out with a group, but it's impossible to talk about average speed since nothing around here is flat; so speed is academic and there aren't enough 60+ riders in my small town to see if I could kick butt or get kicked.

Biggest benefit to cycling in our 60's is the mental and physical well-being that comes with being active. The quality time on the tandem with my wife doesn't hurt and a long, steep climb on the tandem is an irreplaceable character-building experience.

HR BTW: I like to keep it under 140, but when climbing I can sustain 150 if it's not hot. When it's hot all bets are off.

Drafting: Don't care for it much, but I understand the zen. We don't appreciate wheel suckers on the tandem who don't at least say "thanks" when they pass us on a climb.
