Chiltern Challenge

Level B

23rd February 2020

Location: Hambleden Estate, between Marlow and Henley-on-Thames, just off the A4155
Nearest Postcode: RG9 3AN

SI Touch-free electronic Timing.

The event will have SI Air enabled.  If you do not have an SIAC card you can hire one from us for £2.  If you have an SI card (i.e. non-Air) you are welcome to use it if you wish. Your time, however, will be longer as a result, maybe by as much as 2 seconds a control. Our firm advice, therefore, is to hire a SIAC card for the event.
