The nice thing about building a base is that time doesn't matter. This whole week I have not taken a watch on my runs. No added pressure of performing each mile. I know my routes, I know how long they are so it's nice just be out running and being healthy.
Today I ran about 6 miles on a new route that I'll call Lone Tree. It's a loop trail run with a little elevation. Ran for about an hour. Midday run because it's been so cold, today about 30 degrees at 2 p.m. with a little cold wind and snow on the ground. Fourth consecutive day running and Achilles still feels great, body feels great, and most importantly I look forward to my runs.
