5km Run - Intervals 2 Feb 2011

My shoes on some pebbles after my run today I ran another 5 km today. It does seem a bit ludicrous to do this everyday. Running is now such an enjoyable experience and each run gives me so much satisfaction. Didn't think I would ever say that. Today's run was great and the pain I used to feel on my right calf has disappeared. This time mixed with some interval sprints. The laps are as below: 1. 3:11 2. 3:00 3. 3:02 4. 2:50 5. 2:59 6. 4:27 7. 4:19 8. 4:27 9. 4:02 10. 4:17 11. 4:10 12. 4:07 13. 3:52 14. 3:46 Total 51:29 Lap time 3mins 41secs I ran at an average of 75% of MHR and peaked at 95% during my sprints. Phew. Those were hard. I didn't want to do the intervals for more than 5 laps and settled back to a slow pace for the remaining distance. Still, I am happy that ran 7 laps under my usual 4 mins (especially the last 2 laps- the first 5 as it was sprinting was expected). I would never dream of running at more than 85% MHR for long durations though I think I am either getting fitter or my running biomechanics getting more efficient. Still, it's very gratifying to see that I can average about 3 mins per lap with the bulk that I am carrying. If I can achieve this pace running at about 80% MHR (which therefore makes it sustainable over long periods of time) then I'd be running the 5 km in 42 mins easily which is a pretty exciting thought. Of course, if I can run it at 2 mins then I would run the 5 km in 28 mins which is even more exciting. Let's see what happens in 3 months.
