I go to a friend's house in Portslade on Tuesday nights, to play games. The games are good, and the company is good: it's relaxing, etc. It's a good idea for me at this point in time. However, if I run to the university railway station after tai chi, it takes me 33 minutes to get to Portslade station, most of which is spend on Brighton platform waiting for a connection. Then, I have to walk five, maybe ten minutes at the other end to the house.
This week, since my bicycle is working again, I cycled from uni instead. Door to door (so to speak), at no great speed, in a headwind, it took me 48 minutes. I think I can get that down a bit, and at that point it becomes worth doing. I can, it seems, cycle faster than a train (so long as the train stays still for a fair while before setting off).
Cycle to work, to Portslade, home again, with Tai Chi in the middle somewhere. It's tiring, and a little painful in places. This means it's probably good for me :)
