I'm afraid I ditched Laura for the big run. I listened to Laura on Monday night and took in all the advice about breathing and pacing but decided that the music was too awful to motivate me to run 20 minutes. I used jog.fm to create a playlist of songs at pace 8 and went out and ran to my own music. I set Nike+ on the ipod to 20 minutes and started it up after my warm up walk.
The first five minutes were the hardest. After ten minutes I was feeling so proud of myself for running ten minutes and being half way. I knew at this point that I could do it. After 15 minutes I felt great. Nike+ lets you know when there are 5, 4, 3, 2 and 1 minute left so that really helped. Plus running to my own music helped too.
When I loaded my results to Nike+ I found out that I'd run at a pace of 7.5 min/km which may not sound fast but to me it's a great achievement.
Can't wait to get out there again on Friday.
A big thank you to everyone in this community for sharing their experiences and encouraging me to get this far!
