Firefighters had to carry a mountain biker down some rough terrain after he fell and broke his collar bone Thursday at Mission Trails Park.
The rider took a jump too hard and flew from his bike just before 2 p.m., according to San Diego Fire Battalion Chief Mike Finnerty.
Passers-by with a cellphone called 911 for help.
A collar bone break is not one of the more severe injuries, but you can't move it.
"That's not one you walk out on. You're going to basically sit down and request help and wait for it to arrive to take you out," said Finnerty.
Firefighters loaded the man onto a stretcher and carried him down the trail.
Finnerty wants to remind hikers and bikers that while you're enjoying the outdoors, be prepared to in case you get stuck somewhere for a number of hours. Bring plenty of water, cold weather clothing and a cellphone to request help if it's needed.
