Just got back from a lunchtime run which I had to get in as I have plans for dinner tonight but still wanted to get some kind of exercise in today. I usually spend my lunch breaks reading a book but the run to the town centre and back was much more satisfying.

I did another 4.2 miles. It seems I am destined to run 4.2 miles. I didn’t pick a particular route, I just set off from work and ran and roughly aimed my circular route back to base at about the 15-20 minute mark, and 4.2 miles is the outcome.

The distance was achieved in 34.52. and then while trying to find out if that pace is any good I found this neat calculator on Runners world which tells you what sort of time you would manage different distances.

Here’s what I got.

1500m - 7:04
the mile - 7:37
3000m(3k) - 14:44
3200m(about 2 miles) - 15:47
5000m(5k) - 25:20
8000m(8k) - 41:41
5 miles - 41:57
10,000m(10k) - 52:49
ten miles - 1:27:27
a half marathon - 1:56:26
a marathon - 4:02:45

1:56:26 half marathon… Not very impressed with that actually. Although it is below my 2 hours and 6 minutes from the last time I did a half, this time predictor can’t be taking into account increasing exhaustion. I would say that at this pace I am slower than I was all the way back in March.

Must work on upping my speed… Come to think of it I need to up the distances I am running too.

If you compare your 1500m time of 7:04, it is less than half of the 14:44 (that would be 7:22) of your predicted 3000m. It DOES take account of exhaustion. The one proviso it makes is that this is a predicted time with APPROPRIATE TRAINING FOR THE DISTANCE. So, extrapolating from 4 miles down to a mile, you would need to ensure that your speed was OK - for a marathon...

You also need to factor in that the adrenalin of a race will probably cut a few seconds/minutes off as well.
