Oyster/Contactless Time Out?

Hey guys

Thinking of seeing Sarah Siddons this Saturday. If i was to tap in at Baker Street, how long would it take before it times out at the other end at Rickmansworth and i have to pay the max fare? (i would probably be spending up to 30 minutes on the platforms)

Between 130 and 160min (2h10-2h40), depending on time of touchin (whether weekday before 1900, weekday after 1900+saturday, and sunday and bank holidays)

Exact details on the following site

Ah great, plenty of time!

Thanks for confirming
