Steve Rendle's DS Air Ambulance Coast-to-Coast Cycle Challenge 2021 Dorset and Somerset Air Ambulance (DSAA) is a registered charity, established to provide relief from sickness and injury for the people of Dorset and Somerset, by the provision of an air ambulance. I’m supporting DSAA as they receive no direct funding from the Government or the National Lottery and rely on the generosity of the public for support. Their operational costs are over £5 million a year and the approximate cost per mission is £3,000. Target £250 Raised so far £20 £25 incl. Gift Aid Manage Cookie Preferences
