Tonight I did my longest row to date at 150 minutes on the erg (erg is rowers speak for a rowing machine). Covered just over 32km.
Seven weeks ago the longest row I had ever done was 3 minutes as a warm up at the gym and this is a guy who goes to the gym 3 times a year. I've broken that cycle now and have to say I'm really enjoying the rowing. Another couple of weeks and I aim to be able to do 2 x 120 minute rows in a day, so I'm gradually building up.
