its likely then that quite a few major championship medals have been won without the winner necessarily having to dig really deep physically. Most championship races are won well outside the PB's of the top participants. Its tactical, but physically they are virtually cruising, at least until the very end anyway.
25 to 20 in a few months is pretty impressive. Are you doing a lot of mileage per week for this improvement?
If I am trying too hard, sometimes, the arms and legs just go to jelly completely and that is game over and have to walk for 30 secs. Obviously something I am trying to avoid! Do you think this would happen to someone really fit?? What happens to an elite runner if they overcook it do you think? Do you think they "blow-up" in a different way to a "normal" person??
Doing a 5k race tomorrow - first one that is mainly flat and all on tarmac, so will be interesting to see how it goes. Am going to try and "man-up". All others have been parkruns and not ideal conditions. Will also try the intervals above at the weekend as have done no specific training for this, but kind of got the 5k bug recently.
so 8m/m is "conversational" pace for you? Roughly what % of max HR would this represent then do you think?
I definitely think I should be able to get a bit more speed out of myself (for same level of aerobic fitness). I agree about running technique, it does seem to go to pieces as I get quicker, I find it very easy to plod along, but as I try and get faster I think I lose form and become relatively less efficient. Probably partly through poor biomechanics and partly through many years of "plodding" but hardly any speedwork.
