I can't believe that tonight, I ran for 20 mins straight on the treadmill! The first few minutes were tough mentally ("god, another 18 minutes to go? I'm never going to finish this, I may as well just stop now") but as soon as I got past halfway, then 15 mins, I knew I could finish it.
Feeling so good right now and I can't believe that after reading hundreds of people on here worrying about W5R3, or hearing of everyone managing to do the 20 minutes, that I am now one of those people too!
Happy just doesn't quite cover it.
