Thank you for your response, i'll run through the why the personal details are on their:
Age & Employment - Allows active dorset to build a profile of the target audience
Postcode - Will merely be used to determine which route is closest to respondents as ideally we would like the route to be as local, to as many people, as possible.
Email - Allows Active Dorset to contact you with details regarding the start of the running initiative, you will not receive any sort of spam or junk mail.
Non of the details will be used for any other reason than possibly contacting you with an invitation or details of the first event. Hope this helps, any further questions please do not hesitate to ask.
