I was a bit unsure if I'd make it through 20 minutes without stopping, but a bit of positive self-talk and determination did it. Once I got past 10 minutes and I'd turned to run for home it was easier. Amazing how one minute you're feeling like you want to stop and the next minute you're floating along with the music and looking at the scenery.
Also, last week I finally figured out that I need to keep my cadence nice and fast -160-170 bpm - but with a short, light stride, just keep the motor running.
Looking forward to Week 6!
