I used my normal trainers-Asics 1000 or whatever they were at the time (might have been Gel 140s but they change every year). Most people take several pairs of shoes and change them furing the race. And maybe a bigger pair for later on to accomadate swollen feet.
It can be done, just don't expect both of them to be potential pb marathons. If the first one is fast then the second will become hard after halfway no matter how slowly you start, but you could treat the first as a last long run, save your legs and then do a taper before the second and ru that hard.,
I''ve run my fourth marathon yesterday (Chester) in 7 weeks with a spread of 20 minutes between the fastest (the first of those which was a pb) and the slowest (the second-Stratford, 2 weeks later on a hilly course).
Its up to you-how many marathons you've done in the past and what the extent of your training's been. If you've been finding it hard to do 20 mile long runs then think twice. If you can do 20-24 mile runs every weekend 2 marathons won't be much of a step up. Good luck.
It really depends on the length of the race or the time you'll take. Its been a long time since I've run anything longer than 35 miles and on those I just use SIS gels and maybe the odd bit of fruit cake or jaffa cake. Longer runs is down to personal choice-everybody's different. I'd suggest trying easily digestable "normal" snack type food.
Hi, I run with Sale Harriers. There's usually a group meets at the Crossford Bridge clubhouse-just off Dane Road behind the canal- 10:30 Sunday mornings. I don't usually meet up with them there myself, my weekend running tends to be more spontaneous at the moment. But I know you'd be most welcome, as long as you don't mention Trafford AC.
