Intervals

Back to Speed High Walk in the Barbican for some intervals.  10 intervals of one minute fast, one minute recovery.  Was definitely faster than last time

It''s humid, and even after the shower I am still sweating.  The guy in the sandwich shop says
"Gym?"
"Running" I say

Not sure if it was the intervals, the humid day or the shower needed to be a cold one, but the sweaty look at work is not so good.
