Yes of course, the wealth of bridleways in Sussex too - the South Downs Way is probably the best known. I don't MTB myself, so when I'm on the SDW it's always on Shanks's pony - but I meet a lot of cyclists and equestrians there. I don't think there's any conflict although both riders and cyclists do need to exercise a fair bit of etiquette when there are lots of walkers. For the four-legged contingent, going at a gallop or even a canter is definitely out.
I do recall one horse rider going at full gallop along the South Downs Way on a busy Sunday, scattering angry walkers in his path - but it turned out that it was an emergency. Someone else had had a heart attack further along the path, and the rider was racing to the road to meet and guide the paramedics. Normally riders play by the rules.
