PMP my run

[Sweder]

This is very interesting stuff MD. I've always wondered how times measure up over distances. I seem to have a woefully slow official half PB (1:45-ish) compared to my marathon PB (3:52) compared to others. This was highlighted again today when I got another teasing offer to enter this years' TOM. They're grading the starts by race PBs. According to their grading system sub 1:45 half starters will line up on the grid (for the 21.1 k race) in the same area as sub 4:15 marathoners (for the 56K race).

In summary:
10K time 45 mins = 4.5 mins/ k pace (7.2 min/ mile)
21.1k time 1:45 (105 minutes) = 4.98 mins/ k pace (7.97 m/m)
42.2k time 3:52 (222 minutes) = 5.25 mins/ k pace (8.4 m/m)

So . . . my 10k pace of just over 7 minute miling should translate into . . .

. . . oh God, my head's exploded! Hang on . . .

. . . about 8 minute miling, which would give me a marathon time of 3:29.6!

Face it Dan, we're a bunch of slackers!
Hmm . . . what does it say for half marathons?

Ok, it doesn't, but even at the PMP I should be 1:44. Ooh err . . .
