Yesterday I ran around 9.7 miles including a long stretch by the River Cam. I didn’t set out until 4 pm after working about 5 hours on building my pond. It was around 23 C and I took an electrolyte drink which I drank at the half way point, walking for around 2 minutes until I finished it. I drank a lot of fluid when I returned and into the evening. I did some warming down exercises and used a foam roller. I think these all combined to prevent me getting night cramps which have been a problem in the recent past. In the future I will make a greater effort to run in the morning if I’m doing more than 10 K. I felt disproportionately tired in the evening and this lasted into today.
