allmatthew Oct 2023 1:36pm, 24 Oct 2023 120 posts	0 allmatthew Thought I'd resurrect an older discussion on this as I managed to have a good P&D HM training block and it helped me align - not sure that's the right word - my race paces and WAVAs across a number of distances. Based on my best times this year, there's now a 15 sec per mile difference between 5km, 10km, and HM: 5km - 5:55 p/m (72.68%) 10km - 6:10 p/m (70.87%) HM - 6:25 p/m (70.09%) As much as I'd like to extrapolate this to a marathon pace, I know that marathons are the outlier and to a certain extent all bets are off. I've another 6 to 8 weeks before I start a marathon training block so will play around with expected MP to see what feels comfortable. I'm currently leaning to seeing if 6:55 p/m works. That would be HM x 2 + c.13 mins. Based on my last two marathons (where I'd basically worked on too tight a conversion) then my conversion is closer to HM x 2 + 20 mins. Nothing is set in stone, but hopefully it's better to be optimistic than pessimistic!
Bowman 🇸🇪 Oct 2023 1:56pm, 24 Oct 2023 3,105 posts	0 Bowman 🇸🇪 Interesting allmatthew. Here are my stats this year. 5km - 3:35/km 74.23 september 10km - 3:54/km 72.63 April HM - 4:04/km 72.02 may M - 4:26/km 70.43 (not the best effort ) october There are room for improvements for me for sure, i think only the 5k, felt pretty fast for me on the day.
larkim Oct 2023 2:01pm, 24 Oct 2023 22,439 posts	0 larkim My spread is a bit broader this year 5km - 6:14min/mile - 77.16 10km - 6:25min/mile - 74.43 HM - 6:52min/mile - 72.92 Mar - 7:14min/mile - 71.90 The 5km is the big outlier there, which feels odd as I don't feel I'm a short(er) distance specialist!

larkim Oct 2023 4:42pm, 24 Oct 2023 22,442 posts	0 larkim LOL, I get crushed in 5ks in the age group pretty consistently - one of my pet peeves is that there are so many middle-aged men who are still tonnes better than me at running!! Just realised I've made a typo there though - the 5km should read "6:06" pace not "6:14" pace, so that shows the bigger gap between my 5k pace and 10k pace. TBH they were run at different places in my fitness cycle - 5k was about 4 weeks out from London Mara, whereas the 10k was run on a warm June day after I'd not got back into decent volume running. The 5.5 point drop between the 5k and the mara is the biggie.

Ah ok, well I feel that way too, in my age group M45 there are a lot of old farts having their time of their life doing marathons apparently. In my last marathon, a very small one, 380 people or so, there were 11 blokes in M45 ahead of me. All under 3h 😄 The 6:06 vs 6:14 means nothing to me, but I’m getting better at minute miles 😂 Yes there is of course different kind of efforts. But it will be hard to get in 3-4 perfectly executed races in different distances over the year. I’m also a bit careful with the short ones since they are harder to the body.
larkim Oct 2023 5:11pm, 24 Oct 2023 22,445 posts	0 larkim 3:47 per km vs 3:52 per km. Or in wava terms it would be the difference between 77.16 and 75.37.
Bowman 🇸🇪 Oct 2023 5:46pm, 24 Oct 2023 3,113 posts	0 Bowman 🇸🇪 👍 I struggle to convert these things in my head. Calculating time and distance in metric is hard enough, but to add an other distance measure and I’m lost 😂
