For some daft reason I added up the miles I have run specifically for the Brighton marathon 2014 so far... just over 102 miles so far! Yippe. But it should have been about 139 if I'd not had time on the bench. Still, 139 miles past their due date on "the plan", 102 mile completed... about 630 to go. It's a good job we like running
Had another 4 days off following my last run where I thought I'd got away with my plimsoll experiment with just 2 days off just over a week back... fingers crossed.
A mere 8 minutes yesterday to test the water. Seemed to go OK so I did 26 mins today (as an arbitrary catch up). I was meant to be doing jog/run intervals for 85 minutes today but I have blown training so many times before I'm just taking it easy, sneaking back up to where I should be on "the plan". I should be back on track tomorrow if no suspicious aches.
Well my foolhardy plimsoll experiment lead to 2 days rest. I wouldn't say that it was all bad. I think if I'd started my training in them then I'd have built up slowly & they may have been fine. I think if you could get ones with a better top rather than canvas (which would be grim in the rain/wet) then I'd be tempted to use them. They were much quieter than my "normal" shoes. The problem seemed to come from it being easier to run at a silly pace (which I'm not use to).
Anyway, back on planet normal, I picked up with the plan today which said 30 minutes jog. Being a tad nervous after a couple a days off I took it extra easy with 3.1 miles in 33'50". My lowest running HR since I got my new toy with heart rate on it. Good Piggy, no limping required. Yet.
OK, it seems that if you run with a very natural form such as what you get with barefoot or in things like plimsolls the 620 simply can't workout your vertical oscillation.
It can cope with some zero-drop shoes but I'm not really sure how you'll know other than the level of noise a shoe makes! My Anatoms are as noisy as any other "normal" running shoe & the 620 copes fine. My plimsolls are almost as quiet as barefoot & the 620 can't work it out yet it can still tell you cadence (with plimsolls).
It could just be me that's poor with "normal" shoes but assuming I'm somewhere average with form, if your running sucks because of vertical oscillation there could be another way... Just sayin'
Piggyback - imagine what it would be like in plimies after 26 miles!!!! quiet footfall and screams of pain?
I don't think I'd be the first to complete a marathon in them as I think it would have been quite normal pre 1970-ish (or whenever it was "trainers" arrived). But I can see your point, in fact, I may be able to feel it as I've a few new aches now .
