Good luck to everyone taking part in the Brighton half marathon today.
One of the first major halfs in the running calendar, the race is now one of the most popular races in the UK.
This is its 28th year, and rebranded The Grand Brighton, it's now one of the largest running events in the south east and a significant fundraising event for many worthy charities and causes.
Last year alone, the event raised one million pounds.
The Grand Brighton Half Marathon is organised by and is the main fundraising event for The Sussex Beacon, a local HIV charity.
The 13.1-mile race starts on Madeira Drive and will take runners towards the Sea Life Centre.
Runners will then head along Marine Parade towards Ovingdean before continuing onto Marine Drive.
The next stop is the Blind Veterans UK Centre followed by The Greenways Roundabout which will bring runners back towards Brighton on the same roads.
The race then heads inland from the Brighton Palace Pier to St Peter’s Church.
Runners will head back down Grand Parade to Old Steine before arriving back at the seafront and heading towards Hove.
Once they reach Hove, runners will go down King’s Road heading towards Hove Lagoon.
The last stretch of the race will see runners head back down Hove Beach, taking them down Madeira Drive to the finish line.
Several road closures will be in place and alternative routes will be advised to drivers. Times of road closures are subject to change.
Madeira Drive will be closed 4am to 6pm.
