An estimated 2,000 runners have pounded the streets of East Yorkshire and North Lincolnshire in a half marathon raising cash for charities.
The event, which crossed the Humber Bridge, has raised funds for cancer care of young people.
Fun runners at the event negotiated a course that did not cross the bridge.
Organisers said cool weather helped the runners and they hoped the event would eventually raise between £70,000 and £80,000 for charities.
The event has grown in popularity with even seasoned runners describing it as a "tough" course.
Stewart Heron, of the Rotary Club of Hull said: "The runners were all amazingly bullish and grateful for the run.
"They were clearly all on a high and enjoyed the cool and damp weather which made for a race that was kind to them.
"It went extremely well and we'd be disappointed if the event didn't ultimately raise between £70,000 and £80,000 for charities."
