For any non-climbing readers; Top roping is where you set up a rope at the top of the route, and then climb without needing to set up any protection as you go since there is always a rope above you. Trad climbing is where you use tools, such as nuts and hexs, and set up protection as you go, which is a much scarier process since you're often above your last piece of protection (so you can fall furthur), you have to rely on your ability to place protection and you can spend quite some time clinging to the rock with just one hand trying to get the right size nut for the crack!
Sports climbing is the middle ground between top roping and trad climbing, it takes away the need for too much equipment by having fixed bolts on routes, but feels like trad climbing because you are still setting up your own protection as you go (and it still has the scary fall factor!). I really enjoy placing my own protection, but it does make individual climbs last a long time if you're not very quick at it, like me. Sport climbing can at times be even more scary than trad, since the bolts are often well spced out and, unlike many trad routes, you can't 'over protect' (put in more protection then you need to just to make yourself feel better). Since sports climbs need to have already been set up for you, there are only a limited number of places in the UK where it is possible.
So, I was wrong. Sports climbing is fantastic.
That is all.
