1/2 Marathon a week before 1/2 Ironman

Yay or nay? I did not intend it to work out this way, but I was wondering if it would be a bad idea.

It might not be a bad idea, depending on your background and importance of the 1/2IM race.

is 13.1 miles a long run for you? If so don’t do it. If its a piece of cake, go ahead, just don’t race it because you won’t recover in time.

My long run is currently 20, but the half IM is a big race
.

13 miles is not an unreasonable distance to run the week before a half IM, but it is an unreasonable distance to race. If you race it you’ll leave some of your Half IM on that course.

I never pin on a number unless I mean business. I never enter a race unless I am racing. Why pay $50 to go for a training run?

Yay or nay? I did not intend it to work out this way, but I was wondering if it would be a bad idea.

I once did it the other way around. That half marathon was the closest I have ever come to walking off a race course. Just a brutal day.
