Canicross: The people who run races with their dogs
Some people run. Some people have dogs. Some people like to combine the two.
Canicross is a kind of cross-country running with dogs. Runners attach themselves via a harness and bungee-cord to their canine friends - and then race.
As well as the exercise element - owners seem to enjoy the bonding it creates with their animals.
Canix UK has been running events for nearly 10 years and has seen a spike in popularity in recent months, with more clubs and events popping up around Britain.
Organisers say dog welfare is paramount, with running only allowed when the temperature is suitable and say the dogs love it as much, if not more, than their owners.
BBC News attended a race in Hampshire to find out what the appeal is.
