I went out to day to complete my W8R2 feeling really good about myself for getting this far. I set off but could only manage 15 mins of running before getting really out of breathe and having to walk. I don't think that I was running any faster than W8R1 so I am not sure where I have gone wrong. This is the first time I have had to give up on a run and I am wondering if I have reached my limit. I will try again tomorrow, but am feeling really down now.
