48 days to half-marathon (Monday)

My last training was on Friday evening when in unpleasant rain I was testing Garmin Forerunner 305 , newly borrowed from my friend Jacek. I love this toy! In my everyday life I am so used to being kept up to day that ability to see 4 different information like for instance: time of run, distance, heart rate and rate number of minutes per kilometer.
I always liked statistics and numbers so I hope that Forerunner will give me extra motivation to run more kilometres every week. For the time being though all I found out is that I am significantly slower than I expected. I thought that I am doing some 5 min. per kilometre but in fact running 1 km takes me on average between 6 and 7.
Unfortunately the weekend was cold and I did not sufficiently warm clothes so today instead of opening a week with spectacular run I open it with, not so spectacular, cold.
But now in the afternoon I feel better, I don't want to risk going for a run but at least I'll do some rowing on a rowing machine, additional advantage is that while rowing I can both keep an eye on Skype and email and watch a movie on another screen :)

48 minutes and 5 km of rowing later :)
I have rowed for 5 kilometres and already feel much better. I like in rowing that it exercises almost entire body - I can feel nice tiredness in my hands, legs, arms, even back and abs. The only problem is that rowing uses much less calories than running. In comparable period of running I would use some 600-700 calories and while rowing I used just a half of that.
