Walking for people who can't

I've just had to have a 10-minute power nap to recover from this morning's 11km walk up and down Milford and Forrest Hill. Last weekend I did 13km on the flat at Point Wells and Omaha. Both these walks seemed quite hard and were only half the distance I will need to do on October 28! I definitely need to invest in some new shoes this weekend - and blister plasters.
