Another 13 miles

Bad weather and still achy legs decided me against running today. Instead, had a strenuous walk through the Wintry Woods and have now just done 13 miles (20k) on the exercise bike. Amazing how easy it is to cycle a distance that takes me 1 hr 45 or so to run. Really must get out for an easy run in the next day or so. Something off road would be good, so my knees don't take too much of a hammering - my right knee was sore on Sunday's long run and started hurting again towards the end of this evening's cycle.
