Yes, although I like much of susu's definition, I still think that competition is an essential part of sport.

Mountain climbing. Various funsports (which doesn´t mean they won´t be in the future, it took quite some time for Skateboarding, BMX and Surfing to develop competitions for instance) and even some of those that do have competitions don´t depend on them (that there are quite a few professional Skateboarders that haven´t taken part in competitions in years is a good example. In some cases it´s been decades even!).
Of course you could take a broad view of competition and say that somebody climbing a mountain is competing against geography or that a Sufer is competing against the waves. But in that case you end up with the definition I gave earlier: Trying to push your own limits. It´s also worth noting that some people are so far ahead of everybody else in their discipline that the competition against other athletes isn´t important any more. They compete against their own records.

Competing against her/himself, fair enough, more of semantics than real disagreement it seems. My bad. Mounting climbing is a good example, always made me wonder why they do it, aside from adventure/discovery. Do other animals sport?

Can sports involve animals , like horse racing?

A pastime or leisure pursuit is anything you do for enjoyment;
A game is a pastime that involves rules and competition;
A sport is a game that has an organisation to enforce the rules and/or record the results.

So, if you use a racquet to bang a ball against a wall, you are taking part in a pastime;
If you do this under a mutually agreed version of the rules of squash, you are taking part in a game;
If your game is part of a league (a "squash ladder"), you are taking part in sport.

If you are riding a bike, it is a pastime;
If you race your pal to the next lamppost, you're taking part in a game;
If you take part in an organised race, it's sport.

I'm certainly not claiming these as definitive but they are what I use to differentiate.

Yes, I like these definitions.

However, I like to play sports on weekends — usually a game of rugby to pass the time.

If you don't sweat; it's not a sport, it's a skill.
