Still time to get involved in today’s Saffery Rotary Walk

But chairman Simon Milsted said there was still time to get involved.

‘Families can come along and join in the last legs, even on the day,’ he said. ‘If they pay £40, a family of four will all get hats and finishers' medals.

‘They can start at noon at Chouet or 2pm at Bordeaux. Just head on down to the checkpoint.’

The walk was due to start in St Peter Port at 4.30am and more than 1,000 walkers are taking part – the most in the walk’s 25-year history.

Over that time the event has raised more than £1m. for local charities.

One such charity is extra care housing at Rosaire Court, whose residents are taking to their car park to collectively walk the 38.8 miles of the event in solidarity with all those taking part in the main event.

‘That’s the spirit of the walk right there,’ said Mr Milsted.

Between his volunteering duties on the day, Mr Milsted is actually taking part in the walk himself.

He is one of seven past presidents of the Rotary Club each walking a leg in a relay team, to celebrate the organisation's 100th birthday.

He said he hoped people across Guernsey would come out to show their support for everyone involved.

‘There will be a flash of orange across the west coast,’ he said in reference to the brightly-coloured t-shirts the walkers wear.

‘A great place to go to watch is between St Peter’s and Bordeaux.

‘The walkers are on the last leg and really need that support.’

The weather for the walk looks much cooler than last year, with the Met Office saying it is expected to be cloudy and misty with a few showers and a maximum temperature of 20C. Walkers can also look forward to only light winds as only a gentle breeze is forecast.

The first finishers will cross the line in the late morning but others will slowly be making there way across the line as late as 9.30pm.
