Well, that course I thought was 11 km must not be.
The pace was fast enough that pushing it would cause my legs muscles to tighten up, but it was maintainable. That's what I understand running physiologists call the lactate threshold. I started cold, so the median heart rate was probably more like 176 bpm.
I felt fine. Didn't try my new shoes. Too much melting snow and mud.
