This isn't a tri question, but I'm posting here because it's a multi-sport training question...

I'll be 50 in November and I want to do something to commemorate that event.

Two weeks before my birthday is my local marathon/half. I'm only thinking about doing the half. Right now, my long run is 7 miles.

Three weeks before that is a very tough local two-day ride. One that I never had the nerve to do even when I was racing. But it's pretty much The Ride that locals have to do to prove their mettle. Last year, my conditioning was such that I probably would've been able to finish one day, but it wouldn't have been fun, and I definitely couldn't have done both.

Now, I don't have any doubt that I could do both events. But, what I want to get a sense of is how much commitment it would take. Having burned out very hard once before, I'm pretty serious about keeping my training half-assed. I don't want to put myself in a place where I'm too tired to do my gardening, for instance. Where I'm going to fret if I'm sick for a few days. And I know DH won't tolerate it if I can't throw myself into a vacation.

I know you all will have some wisdom for me. Let's hear it!
