I am running the London marathon in memory of my step-sister, Jess Whalley.

As most people are aware, Jess passed away in March last year due to a cardiac arrest whilst doing the thing she loved the most, riding a horse whilst at work.

I have chosen to run the marathon for this charity as the work they do could help prevent this happening to someone else.

Every week in the UK at least 12 young people die of undiagnosed heart conditions. Since its formation in 1995, Cardiac Risk in the Young (CRY) has been working to reduce the frequency of young sudden cardiac death (YSCD). CRY supports young people diagnosed with potentially life-threatening cardiac conditions and offers bereavement support to families affected by YSCD. CRY promotes and develops heart screening programmes and funds medical research. CRY publishes and distributes medical information written by leading cardiologists for the general public. CRY funds specialist referral, screening and cardiac pathology services at leading UK hospitals.
