09:54 Brighton train from St Pancras (Blackfriars 10:03, London Bridge 10:09, East Croydon 10:27), arriving Burgess Hill at 11:10. Buy a return to Hassocks. You can get a Super Off-Peak Day Return from London on this route – which is even cheaper than a Boundary Zone 6 extension – but it's marked “Thameslink only” so isn't valid on Southern services to/from Victoria.
If it's more convenient and you don't mind paying the higher fare, you can take the 10:02 Brighton train from Victoria (Clapham Jct 10:11, East Croydon 10:24), arriving Burgess Hill a few minutes earlier at 11:04.
Thameslink trains back from Hassocks are at xx:28 & xx:54; Southern trains to Victoria are at xx:07, xx:17 & xx:47.
After my recent experience with flooded watermeadows I've decided to postpone yet again a planned new walk on the North Kent marshes. This rarely-posted Sussex walk starts with what looks like an undemanding four-mile stretch to Ditchling where the walk notes recommend the Bull Inn (01273-843147) for lunch, although if this popular pub is full you could try the nearby White Horse (01273-842006) in West Street.
After lunch you climb up onto the downs to join the South Downs Way (SDW) at point [5] in the directions. If you're training for an arduous walking trip you might want to stay on the GPS track and complete the (much longer) main walk, but lesser mortals should switch to the directions in Walk Option 6. This is essentially the reverse of the Hassocks – Lewes walk in Book 1: past Jack & Jill windmills, then down past Clayton church onto a footpath heading north alongside the railway to Hassocks station. There's a pub and a café nearby, although the café will probably have closed by the time you get there.
You'll need to bring the directions from the L=swc.108.b page. Unless you want to do the full walk, be sure to switch to Walk Option 6 when you reach the top of the downs.
