This is a post on behalf of Heart Research UK.
Following the Dispatches programme on Channel 4, this is what they have to say:
From Heart Research UK’s point of view, the London Marathon is a fantastic fundraiser for us and one of our top events. Generally as a charity we work hard to keep our costs down and for every £1 that is donated at least 80p goes towards our pioneering work (much higher than many other charities)
Our expenditure budgets are very tight and we do not spend money unnecessarily. The London Marathon will this year hopefully generate £50,000 for us whilst the Golden Bond places themselves cost £345 per place (a total of £6900 for all our GB runners this year).
With travel and accommodation costs for the event weekend (both at the cheapest rates available) this means our costs are kept very low so that the overall total is as much as possible.
