Thursady more biking

Back is a whole lot better but is still gives an occasional sharp twinge. In fact too many for comfort. So another session on the gym bike this time for 40 minutes. I find it really hard to get the Heart Rate up past 140 on the bike.

Strange thing today was my right foot was sore, the same way it had been last week. Now I have done very little walking let alone running, so this is odd. I am starting to suspect that a pair of my work shoes could be causing the problem. Will monitor more closely.
