4:07 here. Not a PB though wasn't aiming for one. Was a good race for me all things considered. Ran a 3:54 pace much of the way (my PB is 3:55) but couldn't keep it up. Wasn't too worried by that, you learn something about yourself with every marathon.
First time I've come through the whole thing injury free (ish). Thoroughly enjoyed the race, agree that the volunteers were fantastic. As I rounded the corner around 10km at Hibiya, I saw the lead runners turning the corner around 21km with the TV car in trail, had never seen this before and it was really inspiring. This was my 4th marathon and 2nd major, oddly 50% of my marathons have now been in Japan. Great country, fantastic race, well done everyone!
"2. Restrictions on Items Carried into the Start Area
There will be restrictions on liquids which can be carried into the start area. Carrying in water bottles, cans, glass / PET bottles is strictly forbidden. Runners can only carry in liquids that meet all the requirements below: (Jelly drinks and energy bars are allowed if they meet the requirements below.) *Unopened products that are available commercially *Single liquid items up to 200ml, including the container *Total capacity up to 400ml (Any number of containers is allowed unless it exceeds 400ml in total)"
There goes my Nathan Speed 4 Belt then...? Have used this on all previous marathons with no problem - this restriction seems excessive to me. The metal detectors are fine but come on...
Did longest run on Monday of 19 miles. Training has gone alright, probably better than last year but getting rather demotivated about these long races, that's really affected my performance. Had a good half marathon in Hong Kong a few weeks ago (a smaller event than the main one), a hilly bugger at 850 ft ascent but ran it well. Relatively injury free this year though haven't been pushing it as hard.
Jonah - interested to know how you got on booking flights and hotel, must have cost a packet, you left it quite late!
I've read a number of things out there about marathon training in hot and humid conditions, about how the heart rate is higher to cool the body, about how humidity slows the process of sweat evaporation from the skin etc. The general conclusion seems to be that either distance should be reduced, or times should be increased. And there are rough guides out there to how much time should be increased.
I'd be tempted to go for an increase in time rather than a reduction in distance, because I don't want to lose distance training for the full marathon.
My question is how hot and humid weather across a whole marathon training cycle affects training for that marathon, rather than one or two "hot and humid days" (I'm not doing my training in the UK as you might have guessed), which is what most of the stuff I've read seems to budget for.
In other words, if I adopt a whole training cycle which has increased times on all runs to allow for heat and humidity, does this mean that I am likely to run a slower marathon than if I had trained for my normal marathon pace in normal weather conditions? Or should I be just as well prepared as if my training had all been in normal conditions? Although my whole training cycle is in hot and humid conditions, the race itself (Tokyo 2015) will be in winter and it'll be cold.
