Revival is a completely different venue to FOS its period racing with everything set up that way around the circuit. Pathways are very undulating and bumpy (flint and chalk) once you get beyond the start line all the way round the track. Resembles an old uneven farm road. Ear defenders at that age are a must (its very noisy). There will be prams of course, just hope you have a good set of springs. Will be there myself Sunday so enjoy.
Been going for 15 years now, never miss it. One of my favourite days out all year.
