My fitness challenge is going well. Since starting on Saturday, I have walked approximately 26 miles.
However, getting a bit concerned as my right knee is feeling a bit weak. So need to build leg strength.
That involves building in time after my morning walk to put a cold pack around each knee for about fifteen minutes. Also, spend time doing the recommended knee strengthening exercises (see video below)! Then in the evening, repeat the exercises and put a heat pad/warm towel around the knees for half an hour.

Another thing is to stick to the 3 to 4 miles goal during the work week and then one long walk at the weekend. Because as much I might feel like an energiser bunny at times and want to keep going, I need to pace myself so I can go the distance with this challenge. Key to that is building knee and leg strength.
