Today I've had slightly tender patellar tendons and quad insertions. Interestingly both legs are affected. Not bad, but noticeable.
Is this due to a combination of fast-ish run on Monday followed by Wednesday circuits (with a fast-ish run there) or due to wearing the red Brooks shoes for the circuit run and session? Neither is great as I hoped I was getting a bit stronger. When I wore the red shoes some months ago I set off problems but with hindsight thought I'd been deliberately heel striking to feel the cushioning; yesterday I made a real effort not to! I think the safest option is a combination of 2 days rest and put the red shoes back to one side.
