Intervals along the Thames

I did intervals this morning, switching from 6 x 0.25mi to 4 x 0.5mi, with 1 mile warm up and 0.25mi rest in between. Trying very hard to get myself to sustain a faster pace for longer periods of time, and I hope I can get to mile repeats before the half marathon.

The intervals felt hard and my Garmin kept telling me to 'Speed up!' but they were good reminders for me to keep pushing. Hopefully it will be easier to keep pace next week. I love doing intervals outside rather than on the treadmill--it's such a different feeling trying to push the pace yourself! Will do this session  for a few weeks before upping the interval distance again.
