On Sunday, I went for another 1.5 mile run. This time I made it round without stopping or walking!!! Progress.
Today I cycled in to work (5 miles). Also had to pop to the local town center at lunchtime (another 3 mile round trip).
I emailed my Sensei today to ask if it would be OK to go back and train "lightly" with him on Tuesday's. He said he would be very pleased to see me back at the dojo. So, tomorrow I will return to the dojo and do some "light" / "no contact" training. I'm very pleased about that!
There's nothing quite like wearing your Gi in a proper dojo; with a nice wooden floor; and throwing your arms and legs around for a couple of hours :-)
