An exciting all day fun-packed 'It's a Knockout style' event comprising a Corporate Challenge in the morning and a Family & Friends Challenge in the afternoon.

The Family & Friends Challenge is what it says! Approximately 20 teams made up of family & friends. Many of our teams have supported this amazing day for the last 7 years because they have had such a great day while at the same time helping to raise money for Cancer Research UK.

The games themselves are run by a professional events company. You can see from our photo galleries (check out the link) that the huge inflatables, some wet, some dry, are loved by everyone!

Each year our Ultimate Challenge is supported by a corporate sponsor in association with the Jonathan & Jennifer Harris Charitable Trust which has supported our event since its inception.

On Sunday 9th September 2007 we held our 9th 'Ultimate Challenge' in the beautiful grounds of Haberdashers Boys Askes Boys School, in Elstree, Hertfordshire. For the 9th year running the sun shone all day for another fantastic charity family fun day event.

A huge and very special 'thank you' goes to all the participants of the teams for helping to make the day such a wonderful success both socially and finacially.
