I was doing quite a lot of weights i pre season (for football) so upped my protein intake. Not doing much weights as training (both sport specific and running) takes up the majority of my time so I needed something to recover quickly after games/training. There is lower protein and more carbs, Im not sure if you are a 'pure' runner but this works for me. It tastes great too and think I worked out it is only about 50p a go though the tub it comes in is massive which didnt go down too well with the missus (its lie one of those 10 litre paint pots).
I was given the 305 by my OH for my birthday a couple of months ago and it is great. I was using the timex bodylink but the 305 is miles better. Cant really wear it as a watch as it is a bit big but I highliy recommend
I used to use bodyglide and I was runnign a lot when I was in Cyprus and that seemes to wirk well. That said, I now use a base layer top for most of my training which stops any chafing
I had something similar (see my post). It may be worth taping with zinc oxide. I get the hot sports from about 3-4 miles in which can be uncimfortable to say the least on my long run (7.5miles)
