Not all long workouts are the same...

If you read the books, they tell you - especially for IM training - that running is the hardest thing on your body.

In previous years, at lower volumes, I haven't really faced this much.

But this year, 3-5 hour workouts are no big deal.

Except the 3 hour run.  First of those just the other day.

Definitely the most wearing low-moderate intensity workout so far this year.  Oddly, it seemed more so than just 15 minutes shorter.  Now, I'm not completely wiped out or anything, but it was a lot more than just a 3 hour ride, or even a 2/1 brick that was taken pretty hard.  It would get old if I were doing that every week, at least as long as I was doing all the other stuff, too.
