Sam Jacobs, 48, is raising money for the Cancer Treatment and Research Trust by challenging himself to complete a 500-mile run. He works as a partner manager for NetApp, a high-tech computer company

Why the Cancer Treatment and Research Trust?

I am currently raising money for CTRT, a cancer charity based in Mount Vernon, Northwood. I have set myself a 500-mile running challenge and am trying to raise £5,000 through www.justgiving.com/samjacobs500. The goal of CTRT is to raise more than a £1 million by the summer. I chose to run for the CTRT as a friend was having treatment at the hospital where the charity is based. It is a charity based on finding a cure for cancer, and not just drugs to alleviate the symptoms. It seemed like a great cause. I have lost loved ones to this terrible disease.

Have you volunteered elsewhere?

I was UJS chair in 1981 and Jewish Labour Movement full-time organiser in 1982. I also ran the 1996 London Marathon for the North London Hospice.

What do you most enjoy about volunteering?

Raising money for a good cause, I feel good about helping people.

What is your most memorable volunteering moment:

Finishing that 26-mile run for the North London Hospice in blistering heat.
