well done to those on 18 miles with a Planned marathon in April
yes, it all on the day
yes it's total preparation - sleep, drink, food, etc
correct footwear, correct creams for chaffing etc
but now time is seriously getting closer - one CANNOT do much to change your level of fitness, and it's almost time to start tapering
keeping the body gooing by shorter stuff - one will need to arrive FRESH, and not tired or sore or lathargic
TRY to remember, a lot of it is mind games of physcology, keeping the body and mind relaxed, keeping it fuelled
building on a mental stamina, and the way to do thats is sopmewhere out there on a training run, to make it hurt for a short time
building on it all gently, - runs that are little and often can keep the body and mind sharp,
i dont believe its wise as an UN expereinced runner to keep waiting to get in long runs, as they will be painful from the outset - it's all about enjoying what one does
going out HY drated, and witrh a little food in ones belly, and perhaps carry a babana or biscuit, (what ever suits U )
TOP TIP
as marathon day approaches - say 21 days before, STOP experimenting and stick to the devil you know
as if what ever new stuff you eat or drink near to time makes you unwell
then everything will have been for nothing
