I've recently taken an interest in running, but am very competitive and am sick of getting average times in half marathons. I finish anywhere between 2 hours 20 and 2 hours 40. When I train I have no structure and don't really know where to start.
Basically, I need help. Really badly want to break 2 hours but the idea of having to shave up to 40 mins off my run is scary!
Any tips? AIBU to think that as a woman in her mid 30s I can become a brilliant runner?
