A group of friends have raised more than four thousand pounds for the North West Air Ambulance charity.
A total of £4,500 has been raised over a two year period, dedicated to the memory of Gary Wadsworth, who died suddenly in December 2011.
His wife, Joanne Wadsworth, 47, from Caton, Lancaster, wanted to do something good through her grief.
She said: “All his friends thought the world of him. Everyday is a struggle, it is hard. He was my world, my soulmate. We miss him so much but doing this, it brings a smile through the tears.
“It has kept me going, having that aim and challenge has kept me motivated through the grief.”
Gary was a keen walker and was a member of the Morecambe and District HF Rambling Club.
Gary’s passion for the outdoors and the NWAA, convinced his friends and family that the marathons were the right fund raisers for the charity.
The events began in April 2012, shortly after Gary died at the age of 45. Friends of his, Jan Urey and Lesley Forster took part in the Three Peaks, in the Yorkshire Dales.
Rachel Gough ran the Great North Run in Newcastle in September 2012, a marathon that Gary wanted to do. John and Marina Corner carried on the fund raising at the Scottish half marathon in June 2012.
In May this year, Joanne ended the challenges at the Manchester 10k with friends Tony Hood, Jan Urey and Rachel Gough.
She said: “The atmosphere was amazing and friends and family made it special too by being there to support us. I felt that I achieved what I had set out to do and that was to make Gary proud and raise lots of money in his memory.”
