I went for 2 runs while were up there. A 5.5km and a 12.5km run. Both were tough in the heat (30+C) and the hills in Kamloops are killer!
All in all, a great weekend of activity for the whole family.
PS. If ever find yourself in Kamloops in the summer, I would suggest staying at the Thompson Rivers University Residence (TRU Rez). Free parking, free WiFi, breakfast included plus a 2 bedroom unit for $89.95/night.
