Mablethorpe Running Club sent eight members over to the inaugural Boston Marathon, held a day before its world-famous namesake in the United States.
Starting from the Market Place and passing the Blackfriars Theatre out towards Skirbeck, Freiston, Butterwick and Leverton Outgate, runners then headed back to Boston via Freiston Shore and Fishtoft.
