Want ring-tailed lemurs calling your name and stick insects performing cheerleader-style routines as you run past? Bad luck, because this race through the zoo and around Regent's Park probably won't involve much animal interaction. But you will be able to combine sightseeing with exercise and fundraising for the 10K route. April's event raised a whopping £29,000 for wildlife conservation. £50 fundraising target is suggested to all participants.
