Hi Biscuit, Treasur, Marvin.
I downloaded the apps that you suggested and I had time to make train reservations for my hotel destination cities. Now it looks like rain so I will hold off on making any train reservations for day trips. I was on Quora and Dover Castle popped onto my feed.
There is also a Roman Lighthouse.
We had a pair of 90° days this week and the past two days have been filled with dripping wet August humidity. The weather is so strange. So I'm not opposed to overcast with a spritz of rain. I'd prefer not to run in any humidity on Sunday.
I have a couple of options from the airport. I can either take the Heathrow Express to Paddington Station or the Piccadilly line to Green Station or the one prior to it near Wellington Arch. That would be a 5 minute walk to my hotel.
My rail pass says the trip on the Heathrow Express will be free. I still have to pack and I've been too busy this week so it still hasn't hit me yet.
I was looking at Rome, Paris and Dublin for future potential running locations if Tokyo makes me wait for years. Rome would be a cool spot.
So Dover Castle is listed as the best castle in England. Caerphilly is the best castle in Wales and obviously I'm going to Edinburgh Castle but Scotland really seems like it's far down the road.
Thanks for the help
