I can do 5k in about 36mins (being my best) I've always picked nice flat places to run and choosing a nice downy bit to finish on. Over the last couple of weeks I've pushed it up to 6k, but just cannot do ANY kind of hill, and I mean cannot do a hill at all, any slight incline and I've had it, can't breathe puffin n pantin, legs stop working and I have to walk, shame because I live in a very hilly area!! and its getting a bit boring not being able to go where I want.
How do you all cope with the dreaded hills??
