I think we have really got into our stride - long may it continue - I know from reading the more experienced runners that there are good and bad days.
We tried to warm up a bit more with a brisker starting walk than last time, and whether it was this or the fact that naturally we must be building some muscle when it came to the final run my wife didn't get the heavy leg syndrome from week 1 at all and all our runs were at the same slow but comparable pace.
I after feeling a little bit under-exercised have changed my style a bit and found a high-rate small-step rhythm that matches my wife's pace nicely and still works me out well which has helped me.
Next run is planned for saturday - maybe outdoors? We were going to do that last saturday but the weather was unpleasant until evening so we did the usual night-time on road - tried out our trial shoes on sunday though albeit walking not running - lovely walk, nice countryside and views but very very muddy.
