A rescue team was called out twice over the bank holiday weekend to deal with mountain bikers injured in separate accidents.
Bowland Pennine Mountain Rescue Team was alerted on Saturday when a 14-year-old boy fell from his bike at Healey Nab near Chorley in Lancashire late in the day.
He was treated at the scene after suffering shoulder pains and then stretchered by team members to a waiting ambulance.
On Monday, the team was called out again to Gisburn Forest where a young rider had fallen in the difficult Bottoms section on the 8 Red route, suffering severe head injuries.
The Barton-based North West Air Ambulance also flew to the scene and team members joined helicopter crew in treating him before he was stretched to the aircraft and flown to hospital.
The rescues involved 30 volunteers from the mountain rescue team.
Bowland Pennine MRT team leader Kevin Camplin said: “We wish both injured mountain bikers a speedy recovery and wish them the very best for the future.”
