4 miles early this mornig and Hazel appeared as I was getting ready to head out, so how could I say no? She was so excited. I honestly think she could go 10 miles with ease, with no previous training. She pulled me most of the way, until I tugged at her harness multiple times in a row on the return trip and she sort of figured it out. I again forgot calf sleeves/compression socks and forgot to warm up my calf first, so the niggle returned, and continues this morning. I will keep doing concentric heel drops in the stair well and hope nobody else uses the stairs (rarely used above the 3rd floor, and I'm on 4th).
