Hills - more precisely running down them, just did 15.5ishkm as I've the half marathon in a couple of weeks and I'm very ill prepared. Just done a night run and going up Airlie Road was fine but coming down was a killer on the knees.
Have done Airlie Road a number of times both running and cycling. Great route past the cemetery and along the old motorway to Pukerua Bay, but it is a horrid hill.
Yeah I used Airlie to practice hills on the bike also. The Pukerua Bay route, (with a little bit added on), starting at Puk Bay and then down the cycle track through Plimmerton and up Arlie was a really nice run. Going to skip tonight as the knees are still a bit sore and maybe do an 8km run tomorrow.
