Please Post - Interval speed. (Read 743 times)

I need some clarity on how fast I should be doing my intervals. Last week I did 12x400m, 1 minute rest, and I average1:37 per interval. Today, a week later, I upped them to 14 x 400m, and averaged 1:30.5 per interval. Here are my splits: 1:26 1:32 1:29 1:36 1:33 1:32 1:34 1:38 1:29 1:28 1:30 1:34 1:30 1:18 My perceived effort was the same, and both were hard, but i dont know if these are too fast or slow etc? My current vdot according to a xalculator is 47, going off my recent 27:22 4 mile road race. Please help BTW, next week I will be repeating the workout but upping it to 16 intervals and so on till I get to a mximum of 24, but I dont think I will possibly be able to keep the same pace over this amount of intervals.. One last think, I thought I would just tell you I was surprised yesterda, did my longest run eva, 16.21 miles, and could have gone further, but family commitments meant I had to go back home.

1. Why are you running track intervals in the heat? They are far better run in cooler weather.

Butting in, he's in the UK Trent It's like only in the 60's or so.

What's the point of the workout? What pace are you aiming for and why? You should be doing them slightly faster, or slower than that. Or exatly that fast. Or something. Serioiusly. Don't get too fine. Run by feel. Just aim for consistency.

Since your goal race is 10k, I would suggest before adding more 400's you might try jogging slowly for half a lap in between instead of standing rest. Make it one continuous run. And try to work on being consistent, more than being fast. So if you average 1:30 per, try to have all of them fall within a second either way of 1:30. Training should be a progression but you don't need to add volume each week to keep getting faster.
