One idoit one knee problem. Oh why did I have to go for the 7 mile in an hr on the tredmill. From Monday to now and still now a big pain at the bottom of the knee cap. It only started at the bottom left and was not bad but has grown to hurts walking and bending. It's going to be hard to run a 50 in the 1st of April I got to get moving. Hopfully this week to get to a little more cycling to work that out.
