Aimed for 21097m put on deepwater horizon with subtitles....good steady row really felt good until about 13k in when hands started to feel very sore and had to try and adjust position as quite painful...left arm also very tired for about 5k but worked through that. The half marathon distance never in any real doubt....movie on worked v well not watching the clock/metres non stop. An enjoyable row about from hand pain and did it nice and early in day which helped.
