Help for Heroes bikes stolen before Cotswolds triathlon
Bikes owned by injured servicemen were stolen before they were due to be used in a race in Gloucestershire.
Twelve bikes belonging to beneficiaries and staff from armed forces charity Help for Heroes were taken by thieves from the Go-by-Cycle campsite in Somerford Keynes in the early hours.
A 40-strong team from the charity was camping there prior to taking part in the Cotswold 113 triathlon.
Gloucestershire Police want anyone with information to contact them.
A spokeswoman for the Wiltshire-based charity said: "The thieves would have clearly seen a Help for Heroes banner on the tent as they carried the bikes away as it was a moonlit night."
She said that Team True Spirit, the group competing, comprises wounded, injured and sick servicemen, women and veterans from all over the UK who enjoy "ultra sport" challenges.
The Cotswold triathlon was to be their main training event for the Ironman UK challenge, which takes place on 20 July.
Help for Heroes co-founder Bryn Parry said it was "unforgivable that someone might choose to steal from servicemen, women and veterans who have suffered life-changing injuries and illnesses".
Mr Parry added that most of the equipment had been donated by members of the public.
