New one-way systems, temporary road closures in some areas and the introduction of new technology for logging walkers through check-in stations should all help to improve the congestion.

However, it will mean that back-up supporters for each walker will need to make a new effort to resist the temptation to follow their walkers every inch of the route, said Isle of Man Constabulary Roads Policing Unit Inspector Derek Flint.

'This new technology has the potential to further refine the running of the Parish Walk,' said Inspector Flint.

'However, this is dependent on support drivers embracing the changes, and going to predicted points, rather than just following the field.

'Additionally, the psychological support that the back up teams offer can't be under-estimated.'

New technology will mean text messages can be sent to up to two mobile phones per competitor, informing supporters of how their walker is progressing – another measure designed to reduce the need for support vehicles to follow walkers every mile of the route.

The Clerical Medical Parish Walk takes place on June 23 and June 24, starting at the NSC in Douglas at 8am.
