I'm in week 6 of the programme, and feeling really great about the progress I'm making! I never would have imagined 6 weeks ago I would have a 20 minute run under my belt already. My question is, do you guys run on flat surfaces, or do you try to incorporate a hill or 2 into your run? So far I've been running on mostly flat footpaths near my home. Tonight I did W6R2, 2x 10 min runs with a 3 minute walk. It should have been easy peasy as previous runs have been harder...BUT I decided to run in local park which had a few small hills, and I was so exhausted I ended up walking 6 mins into the second run.
Is it better to build up my times on flat and then try to tackle hills - or is it better to get used to hills now and maybe repeat a few runs until I can complete them with some inclines?
