ATM - just got back from 30k and used 3 SIS gels. Never used them before, so went on advice of the guy in Runners World. Took one every 50minutes, seemed to work ok...
Thanks for the advice. I am following MyAsics training schedule - long runs are 32km for the next three weeks, then 19km for the following 2 weeks, then down to 13km the week before the BIG DAY.
Perhaps I should make the first week a 28km instead of 32?
This is my first marathon, I've done 2 halfs and have been training for this since October. I'm now up to 24km and doing my first 32km this weekend. I was exhausted at 24km, so am worried about the push to 32. Any tips?!
