I didn't run the Paris marathon last Sunday, but as usual I watched it on TV. I thought it was going to be too hot because of the blue sky in the morning, but in fact the temperature didn't go beyond 14 degree during the day; so I guess it wasn't a problem for the runners. Watching people running is always a good motivation for training and a good occasion to analyze the technique of professional runners.
About five months left until the Berlin marathon, so I still have time to think about it, but I seriously started a regular training again when my time scheduled permits it.
