Family and friends of the late Andrew McGeown visited Scarborough RNLI to present £3,149.
The money was raised by Natalie Foster and Brooke Trotter, who ran the Manchester 10k race, and Kadie Walker-White and Katie Hoole, who completed the Yorkshire Warrior.
The four runners were part of a large group of family and friends who met RNLI crew at the temporary lifeboat station on the harbour.
Andrew, 32, died in February when he went into the sea to rescue his dog, Arnold.
Lifeboat operations manager John Senior said: “I understand and recognise that it is the family’s wish that all monies raised should be allocated to a local awareness campaign on the dangers of the sea and I can confirm that this very much fits in with the RNLI’s Community Lifesaving initiative.
“On behalf of coxswain Tom Clark and all the crew here at Scarborough lifeboat station, can I thank you for what has been a tremendous effort in raising £3,149 and can I also pass our most sincere condolences to you and all the McGeown family for the tragic loss you suffered, a loss which was shared by the many friends that Andrew had on the Scarborough lifeboat crew.” The total included £1,000 of match-funding from Barclays Bank.
