So I completed the entire C25K on a treadmill a few days back and decided it was time to brave it outside.
Since completing the program I have run outside a total of twice. Each time I’ve not managed to run the 30 mins and had to stop and do a little walk at around 20 mins. I though I might have been going too fast but when I checked my pace it’s between 11.15 and 11.30 miles per min. I’ve only managed a distance of 1.77 miles.
I can’t understand what’s happened, why am I so exhausted outside, it’s completely different to running on the treadmill and I’m starting to think I made a mistake doing the program indoors. Maybe I should start from week 1 again but outside this time?
I’ve also noticed I get major muscle ache in my thighs the following day, maybe I’m using different muscles outdoors due to the elevations?
I’m feel rather deflated, I had thought I’d be able to go outside and immediately run for 30 mins and perhaps beat my treadmill pace of 10 mins per mile but sadly not.
What’s wrong with me? 😧🤭
