2nd day of january challenge, put in 21097m but happy stopping any time after 10000m as would be more than 10000m yesterday which was 645 calories....music on no tv as in front room. Felt really good throughout, steady pace no pushing just seeing it through. Lots of time spent staring at monitor but row went pretty quick arms a little sore 4k from finish but nothing bad and never felt like wasn't going to finish. Fingers a bit sore and may blister a bit. Dont know exactly but first half marathon for a long time. Felt v good after will see if sore tomorrow.
