Went out in the rain at ten to seven this morning, armed with a new playlist which helped hugely. I've discovered a way to find songs with a consistent speed (in terms of beats per minute), which slows me down at the start of the run, and keeps me going at a reasonable pace towards the end.
I realised a few runs ago that Nadine Shah's track Holiday Destination was a good steady plodding pace, and then used songbpm.com to check its beats per minute. Then I searched on jog.fm for songs with that bpm, and set up a playlist on my phone using my music streaming app to play the ones I liked.
No association with either of these websites, I just found them really useful.
