The race - which will take place on Sunday (April 28) - will mostly be run on footpaths and cycleways, however there will still be a number of rolling road closures throughout the morning.
Motorists are reminded to allow extra time for their journey and take care when driving near the 13.1-mile race route - which starts and finishes at South Hill Park.
All places in the race have now been taken.
Organiser Chris Vaal, leisure development manager at Bracknell Forest Council, said: "We put the road closures in place to help ensure the safety of the runners.
"We are aware that there is a certain amount of disruption for local residents, but we will be working with our traffic management company to keep the disruption to a minimum. Roads will be re-opened as soon as it is safe to do so."
He added: "The race receives fantastic support from the local community, which I know the runners really appreciate."
Cllr Iain McCracken, executive member for culture, added: "Runners training for this event will be starting to taper down now, and will be making final preparations for the big day. Good luck to everyone taking part in this sell-out event."
