I took a look at the activities that you had signed up for and taken part in on the day that you had written your post (last Thursday July 12th)
Those were indeed both races. However, that day and the following day were both London days, according to the Course Schedule. If you were using the “World Hack” to revisit Watopia, as your images suggest, then that would definitely explain the issue that you are seeing. If this is the case, please be sure to undo any changes you’ve made before attempting to participate in any events.
I hope that clarifies the situation. If not, please be sure to write in a ticket with this or any other issues that you might be experiencing.
