Don’t get too stressed by the training plans (unless you are going for a specific time), just remember to keep the training as mixed up as possible, speed work, tempo long runs etc. Keep thinking about diet and always take the stairs!.
In my experience (FLM06 will be marathon number 8) if you follow the training plans to hart you are either too knackered or too injured to run the race!.
Rich,
As for the long training runs, just take plenty of water/sports drink with you, maybe also a light snack for halfway round. Its not too much bother to carry.
Remember this time of year the weather will be cooler than April and you probably won’t train at your race pace so you won’t get as dehydrated than as on the day or in your recent half.
Some people go around their route in a car the night before and leave out bottles for the following day – but this seems excessive to me.
BTW, its worth understanding that a Marathon is not two half’s back to back it’s a completely different experience, if you can do a half now you’ll be able to get to 20 easy by April.
