This article had my name on it
As I started training for the upcoming 10k I needed to decide what my 10k goal time would be. I had no idea what to use and decided on 7:24min/mile since I had progressed to that speed in a workout I did which called for 3 1 mile repeats that got progressively harder. I have actually run under 42 minutes for the 10k but that was more than 10 years ago and in my recent sporadic running history have been more around the 50 minute mark. So I figured I'd hopefully be somewhere between that.
Yesterday the plan called for intervals at 30 sec/mile faster than 10k goal pace. I got through the 1200, survived the 800 barely and when it came time to do a 400 just couldn't maintain the pace so I stopped. I couldn't get enough air. So today in my email I get an article in my Complete Running Network newsletter that could have been written just for me.
It talked about how the most common mistake in speedwork is running too fast. They should be a test of the VO2max and something that can be maintained instead of an anaerobic workout that offers diminishing returns. As I reviewed my training for the race I noticed that from the first tempo workout I was remarking that I thought it was a little too hard to be a tempo run in that I didn't feel I had anything left. Since then I have had a few tempo workouts where I haven't been able to complete the whole thing or do a cooldown afterwards. This culminated in yesterday's non finishing of the speed workout.
So I have decided to back off my 10k goal pace to about 7:35 and adjust further workouts towards that level. Being my first race since I started trying to run seriously this is more about finding out what my pace should be rather than setting a record.
