We're taking part in the very first Firefleas ride, a ride marking the 10th anniversary Fireflies ride - It's a charity bike ride all the way around Richmond Park. We're going to cycle all 7 miles to raise money for Leuka - the charity leading vital research into a cure for Leukaemia at London's Hammersmith Hospital.

It will be the furthest we have ever cycled and it's a big challenge but we're going to show our dad who's a Firefly how it's really done. One day he'll be trying to keep up with us!

Thank you again

Grace and Inigo
