Why do I get redirected to Let's Do This when entering a Great Run Event?

Run South London has partnered with Let’s Do This to take event entry bookings. 

When you enter the Run South London event, your entry information and payment is processed by Let’s Do This and passed securely to us. Your bank statement will show Let’s Do This against your event entry and you will receive a booking confirmation email from Let’s Do This, in addition to your usual entry confirmation email from Windermere Marathon. 

All pre event advice and information will arrive in your inbox from Run South London.
