Yes, I know
@tri-man 47 has mentioned that a lot before. But those longer runs won't get me to 80 minutes. We're talking about running 2 miles of warm up, then doing 16x200 and then 2 miles of cool down. I don't see how I'm going to hit 80 minutes with that workout even being slower.
Funny you mention that because I thought of it yesterday when I was done and saw I hit 83 minutes and was thankful for the 3 minutes of specific adaptation I accomplished. If I would have had more time, I could have knocked out a couple more miles.
But yeah, something I'll keep in mind and try for. It's only on those Tuesdays so when I can manage the longer WU/CD, I'll go for it.
