So I am on W6 R1 today but had to run outside as my treadmill is playing up,so off I went confident that it would be ok as W5 went great for me, however before I even got through the first run I was wanting to stop, I managed to carry on and did complete the podcast it but I was close to giving up on more than one occasion. I was puffed out, my legs and ankles were agony and I couldn't wait for it to be over...what has happened? I found that my pace was all over the place, and I had to run on the road as the camber from the drop paths was making it worse for me, and it was slightly uphill at times. I realise that running in the street is different than the treadmill but my god I never expected it to be that hard. To think that I was crying tears of happiness on the phone to my mum last week after doing the long run on W5 ( on the treadmill) and feeling so happy about it, to today feeling miserable because it was a disaster. I have entered my first 5K race in Oct and if today is anything to go by I will never complete it. Would it be wise for me to keep running outside now to get used to it?
