Met up with a couple of Canicross buddies for a run this morning. I took my daughter's beagle, while daughter toddled off with her little boy and my Spaniel (she's getting better every day, but not allowed to do too much).
Both the ladies I was with are faster than I am (51/2-6min/k pace), so we did quite a lot of short sharp runs with walk breaks, which I am totally counting as an interval training session.
Ultimately we only ran just over 4K, but I really feel like I had a workout.
