Weather conditions for today's Great West Run look like they will be cool and cloudy with a slight breeze - perfect for the race.
Thousands of runners will pound the streets of Exeter this morning when they take part in the annual run.
More than 2,700 runners have signed up for the event and will be feeling a mix of nerves, anticipation and above all excitement ahead of their half marathon challenge.
The race will start at 9am on Sidwell Street by the Lord Mayor of Exeter, Councillor Rachel Lyons. Race organisers GO2 are encouraging as many people to go out and show their support for those runners taking to the streets.
Amy Budd, marketing manager of GO2, said: "As one of the long-standing running events in the area, the event has such heritage, and the community always come out in huge numbers to show their support.
"We're encouraging everyone to take to their doorsteps, hand out Jelly Babies, and generally shout and cheer our runners through the 13.1-mile course.
"From elite runners, right through to all those fantastic fundraisers who have taken on the challenge to do something amazing for a good cause, everyone feeds off the support of the spectators.
"It really makes a massive difference to everyone taking part."
This year, the Great West Run takes on a new 13.1-mile route, taking runners down the High Street, over Exe Bridges, through Exwick, on to Stoke Woods and then up to the university.
They will then follow an out-and-back route along Pinhoe Road, and finally join Blackboy Road to finish back where they began at Sidwell Street.
Cancer Research UK and Children's Hospice South West are the official charity partners for this year's half marathon.
In addition, The Schools Challenge has partnered with Make-A-Wish Foundation, where more than 250 local primary school children will follow in the footsteps of the half marathon runners to complete a one-mile run through the city centre.
There will of course be hundreds of runners out there fundraising for a number of worthy causes.
There are six elite runners entered for this year's Great West Run; Jake Waldron from Exeter Harriers, Tom Merson and Lucy MacAlister from Bristol and West AC, Ollie Garrod from Epsom and Ewell Harriers, Kairn Stone Newham and Essex Beagles and Maddie Horton.
Prizes will be awarded to the top three men and top three women, alongside a prize for the top running club.
