Update time I guess!
Will actually get the last two weeks training logs up soon. Basically things seem to be going on track. The achilles is definitely improving (Thursday I was actually able to wear normal shoes with no issues) - but it's going to be a matter of weeks/months until the eccentric dips manage to improve it substantially.
That said am now running pain free in my vaporflys and am gradually increasing the volume of running. I've also finally stopped moping and gotten myself on the exercise bike. It's not perfect but if you're putting in long stints on it, a) you keep the weight down (and I was getting perilously close to a stone above training weight - now it doesn't make a huge difference to my appearance but an extra stone with every footfall - not good on an injured achilles!) and b) it keeps you at least aerobically fit.
Right now with drills, limited running and extensive exercise biking I'm hitting over 2 hours a day training - that's not going to win me any medals but should keep me under 17 minute 5k shape and make a comeback much easier once my achilles is fully healed. I really felt it a bit last few days getting back into semi-decent training - it takes a week or two for the body to adapt- luckily I was at clapham all this weekend so nice and easy to take a midday nap!
One thing I would be fairly interested in is seeing my actual sprint speed in the next few months. Right now 6 days a week I'm putting in 20 minute a day of drills and then a few strides - last time I ended up doing something like this (but nowhere near as rigorously) I dropped a 56 high/57 low 400m despite having very little running under my belt. Not really intending to too but temptation might get too much. If I can keep this up I'll certainly look at doing a few time trials and maybe even doing some running indoors and see if I can get anywhere near 2 minute for 800m.
If anyone knows where to get any shoes (or any models) with a very flexible heel cup (or very cushioned) - a la the Nike Vaporflys please let me know - currently they're the only ones that don't manage to completely shred my achilles at the moment.
Training log up very soon. Haven't done the final calcs but next week the total training volume (running/drills/ex. biking) will be good I hope...
