I did something a bit different today. A 4km warm-up/down.
In between I did 8 x 1 minute efforts with 1 minute walk recovery. I ran them at 10km pace, maybe a bit quicker. I was wearing my heavy joggers which is always a bit of a handicap.
I estimate 10.4km for the session.
Watched the Boston Marathon today. A good finish to the end of the women's race with the Ethiopian just hanging on.
