Is it just me or do intervals make others dehydrated and headachy too? In a good way. They make me feel like I am getting a different kind of workout. A hard one. A good one.
My thinking about intervals for marathon training has changed. When I first started training for marathons (3 years ago) I didn’t think there was a place for them. It seemed crazy to me that running a few 600m intervals could help in a 26.2 MILE race. They seemed to take too much out of me and not be of much benefit, IMO. So I didn’t do them. Now I feel differently. I know they are supposed to help with the whole VO2 max thing, but my rationale for why I think they are helpful is much simpler than that. They help me because they are crazy fast. So then when I’m running my marathon pace, it (MP) seems slow and easy. So back in the schedule they go. And I love them. They are fun!
8 miles done today, with 5 x 600m (6:56 pace) with 2 minute recovery jog between sets. Also included a couple of downhill miles. Fun stuff!
