well, I just couldn't get it 'going' - I mounted ok, but only went a couple of feet before losing balance. I was in a public park, a couple of people were watching me, it was kinda embarrassing. Don't have the bike anymore, sold it...
Anyways my running is progressing, last night I went to my local mall and back - a distance of 2.3 miles, covered in 27.5 minutes. Today on a treadmill in the gym I covered 2.5 miles in 30 min.
So far, I have had no issues with my joints, the only issue is with the muscles in my thighs which are a little tender for a couple of hours afterwards. I am guessing that my joints have had bout 7-8 yrs to adapt to a weight that was 220lbs+, now I am 212 it takes the pressure off my joints a little, their athletic bearing capacity is increased. Mind you, 12 lbs ago I tried jogging, only lasted about 2 minutes before my left knee began to hurt. But, no problems now...
Now that I am interested in running, I am considering entering the Sydney City to Surf in August. It is 9 miles, some decent hills, thousands enter it. It is 6 months away, plenty of time to train.
