For the past 6 or so months I've been running and graduated from C25K on a treadmill which has been fine, no issues at all. I've been regularly running on this gym treadmill at roughly 10kmh with no issues (my best 5k time on treadmill is 29m30s)
However this morning I went to a new gym, set up my treadmill as I would normally (10kmh) and I had to give up after 5 minutes! It was super difficult! Sweating more than usual, my earphones kept falling out, it was a disaster!
Just wondering if anyone else has ever had a similar experience changing between treadmills? I was just shocked as felt like even though it was the exact same speed and conditions I was suffering so much!
