Runners?

[SeanPrest]

i also have had knee trouble in the past with road running so i took up trail running. make sure you get a very good pair of shoes, they make a huge difference. trails are alot easier on your knees as the ground has give unlike paved roads. not sure what options you may have in lethbridge but on mountain trail/ road mixed race i was able to do 30km which i would not want too do on road alone.
