Went for my Week 2 pt. 2 run today. Didn't stop at the 25 minute threshold as I felt like I could go on, managed to run to 40 mins using the same 90 second run, 120 second walk. I could have gone further but felt a tightness in my knee so I came to a halt and felt really proud of myself considering the fact that my legs started to ache a tad withing the first 90 second run segment. I have made my own playlist and altered it to suit my mood at different parts of the run, it's really helping me as I just want to soldier on when the heavy drop comes in a dubstep/drum and bass tune. I am just concerned at how my legs are aching so early into my run! Bare in mind it is only week 2 and that I'm using a treadmill. I hope this blog post can inspire other runners at the same point in the program as me.
