Sunday was a steady 15 miles on the Derwent Walk. This was my longest run since returning from holiday and took my weekly mileage up to the 50 miles I had planned and was a reasonable increase on last weeks mileage. Unfortunately it also saw the recurrence of my recent knee problems, with my right knee swelling up. As a result I headed for the Gym tonight and did an easy 3 miles on the treadmill. Thankfully there were no problems so I intend to get back to some speed work tomorrow.
