Good idea. I was planning a bit of Parkrun tourism this coming Saturday (up North: Guildford!) but maybe 26th May? (If you can't do 26th I can switch to the 19th, no prob.) Worthing's good for me of course.
Did the Portslade Hedgehoppers 5 yesterday. Out from the back of Portslade to Devils Dyke. Not as hilly or wet as I feared (I am a total wimp) but very narrow paths and difficult to overtake if you lined up too far back. Great little run though. Aimed at 40.00 and got 40.13 so OK. 5 miles feel a long way when all you do is Parkruns!
It’s one of the West Sussex Fun Run league events........they’re all very similar. Mostly offroad, always sociable and friendly and very cheap to enter. Open to all, you don’t have to be associated to a member club - fixture list here (ignore ‘2016’ in the link, it takes you to 2018) :
