I found it considerably easier on the treadmill. Do you think this is just because the programme is working or is it easier because I was on the treadmill?? The main difference I know of is I struggle to keep a constant speed running outside, I often run too fast and walk too slow, on the treadmill I had number 5 for walking and number 8 for jogging so I know I was being more consistent with the speeds.
Thanks in advance.
