Tempo run

I took HRM with me in order to keep the pace down. Usually I just try to push it too much this close to marathon. I could of course let tempos be, but... Do I have to learn new tricks??? Anyway, I ran 6.2 miles (36.40, last 2k 7.00) with no mentionable effort. Suprisingly, pain was not there. I don't miss it at all.
