Some competitors have raised security concerns after a reorganisation of the TT paddock placed their living accommodation apart from bikes, tools and other equipment.

The reorganisation follows the latest health and safety review held after last year’s event.

One competitor, who asked not to be identified, said he was concerned about leaving a racing bike and thousands of pounds worth of equipment distant from his accommodation, particularly if there was no enhanced security.

’We understand caravans and camper vans will be down behind the snooze boxes and the awnings where teams work will be separate in the old grassed area (near the dog walking area).

’Our understanding is they don’t want the bikes and working areas to be near to the living accommodation,’ he said.

’But I’m not happy if it means leaving a £15,000 bike and £5,000 worth of tools 500 yards away in a different area.’

A spokesman for the TT organisers said changes were recommended to working practices and facilities in the paddock.

The most obvious change for spectators will be moving the main paddock area, originally situated on the north side of the Hailwood centre by the parc ferme, to the hard standing behind the stalls and beer tent, while for competitors, living and working areas are separate.

But a spokesman confirmed fans would still have the same access to teams and riders as in previous years, including access to the main paddock, where the top teams and riders are.

Security concerns have been raised in the past at the TT paddock where organisers have to strike a difficult balance between allowing open access for fans but keep valuable bikes and equipment secure. In previous TTs there have been claims that bikes in the park ferme had been tampered with and Manx Grand Prix winner Jamie Hodson had a bike stolen at a race meeting held at Aintree in 2015. No information on paddock security was available at the time of going to press.
