The Yorkshire Air Ambulance had its busiest weekend in its 14 year history when the Tour de France came through the region.
The charity was called to 10 incidents on Friday and a further 21 over Saturday and Sunday - compared to just three callouts on a normal weekend, with many linked to the Grand Depart.
A third helicopter was drafted in to provide extra coverage.
Abby McClymont, YAA marketing and communications manager, said: “We knew that we were in for a busy few days with the excitement of the Tour de France coming to the region, however this past weekend has been one of the busiest for the Yorkshire Air Ambulance.
“Our two helicopters, along with the third extra aircraft and their crews attended 21 incidents on Saturday and Sunday alone. We have had many busy weekends in the past, but nothing as busy as this last one has been.
“We were pleased to be able to work alongside the other emergency services and help out where required.”
She added: “We were called to a few people who had been out cycling on the route, or were on their way to watch the race and unfortunately found themselves needing the air ambulance.
“Other incidents included spectators who developed health problems whilst waiting for the race to go past.
“However, generally, we attended the same kind of jobs we would usually do, but just in a greater volume due to the vastly increased number of people in the region over the weekend.”
Two helicopters operated from their airbases on the Nostell Estate near Wakefield and at RAF Topcliffe near Thirsk, while a third was operational from stand-by points close to the route, at Wathgill Camp near Richmond and Beeston Hall Farm, near Ripponden.
“As well as being busy operationally, we were also busy with lots of Tour de France related fundraising events,” added Abby.
“The atmosphere along the route was fantastic and Yorkshire has a lot to be proud of.
“We would like to sincerely thank everyone who has supported us, especially over this weekend.”
