Two big events are taking place in the Vale today – the Race for Life and Chiltern Hills Vintage Rally.
This morning there is the Race for Life at Waddesdon Manor, a 5km running event in aid of Cancer Research UK.
The run starts at 10.30am around the picturesque Waddesdon Manor estate and although there is a steady incline at the start there is a long downhill stretch at the end.
Entry costs £14.99 for adults (women aged 16+), £10 for children (girls aged 6-15 & boys aged 13 or under) and entry is free to boys and girls under six.
There are also activities for families and spectators in the form of face painting, food outlets and merchandise.

The annual rally is organised by The Game Club and raises money for local charities.
As well as a display of more than 800 classic vehicles, other activities include children’s rides and slides, a dog show, around 50 trade stands, a beer tent, a pig roast and refreshments.
Entry to the rally costs £6 for an adult with under-14s getting in free.
It also costs £10 if you wish to bring a vehicle on the day.
