Mountain biker Simon Harris, 40, died three days after being found unconscious on the Ridgeway between Hackpen and Overton hills, an inquest in Trowbridge heard on Tuesday.
Mr Harris, an information technology administrator, was found lying by his bicycle and broken helmet on a flinty stretch of the track by two walkers who called for help.
By the time a paramedic arrived Mr Harris, who lived with partner Joanne Cooper and their son in Grange Hill, Swindon, had recovered consciousness and was able to walk.
He was taken to Great Western Hospital but had slipped back into unconsciousness by the time he arrived. Three days later tests showed he had suffered brain-stem death.
A post mortem showed he had suffered an arterial thrombosis.
Wiltshire’s assistant deputy coroner Ian Singleton concluded that his death was an accident.
