Sorry for being a running tart: I'm now out in the USA running with two of the three clubs I am associated with here. The one I'm not running with this time is my favourite, http://www.thereservoirdogs.com/, who run round Central Park.
So as bus says, he left me way behind: 19:15 for 5k so the last 3 have gone 18:14, 18:50 and 19:15 which is the wrong way. Legs are just tired but it isn't a lot of miles: 40 a week and 6 days so pootling along. Hope that it is just the non-running related work that is making them tired: long days doing family stuff including a 500 mile drive in one day to move furniture round the UK.
