It's always nice to have gotten some sleep on call meaning a post-call day can be useful.
I did so serious work on my research project, and then went down to the gym what turned out to be my longest run ever.
I ran the first 3 miles at a steady rate increase. Then I ran each of the next 3 miles as intervals: walked the first 0.2 miles, then starting running and increased every 0.1 miles. I was ready to do the 7th(!) mile in the same manner but my hamstrings had had enough, so I walked out the last mile.
That's 20.5 miles for the month, and I'm back on track to complete my goal of 35miles for March, plus few extra.
The sunshine really tempted me to get outside, alas it's still only about 35 degrees.
