5000 miles, chain will be worn and the cassette probably. I wouldnt bother cleaning them, just replace.
Do you use wet lube on the chain? try a dry lube, or a wax if youre not going to use the bike outside in the wet, and give the chain a wipe over with a cloth once a week to get rid of the excess lube and top it up when it needs it.
My summer bike gets the chain wiped after each ride (plus a general wipe over) plus fresh lube about once a fortnight.
The winter bike gets wet lube so a clean with medical alcohol and a top up after every ride otherwise it gets full of crud. It gets used in all weathers.
Just bought a dry lube myself funny enough, was going to give it a try as I have a bike that never leaves the trainer. Might actually change the turbo tire as well, making more noise than usual and definitely v worn
OK, only me and Ryan have done it, and Ryan didn't know he was in a competition ... but even so 

The rest looks OK ... 2 x 10 mins at 228 watts should be easy, but after that initial sprinting I'm not so sure 

11 minutes faster than me
(for now)
