Get your running shoes ready, we are two days from the 42nd annual Beach to Bay relay marathon. Last year more than 12,000 runners took part and just as many, if not more, are expected this year.
The 26-mile route begins on Padre Balli Park runners then head over the JFK Causeway then through NAS/Corpus Christi. From there, they'll run down the Bayfront along Ocean Drive. The run ends at McCaughan Park and expect a lot of traffic changes because of the marathon.
The city and police want to make sure all the runners are safe and all the drivers are prepared for possible delays. The signs have been put out alongside Park Road 22, warning anyone heading to or off the Island to be aware of the thousands of runners they'll be sharing the roads with this Saturday.
The run kicks off at 7 in the morning but the city plans to implement its "traffic control plan" at 4 am.
Here's what to expect if you'll be driving anywhere near the marathon route:
Parts of Park Road 22, southbound, will be reduced to one lane and on the northbound side of park road 22, there will be shoulder lane closure.
Both northbound and southbound sides of Shoreline Blvd will be closed until after the event and expect some side street closures along the route as well.
Speed limits won't be changed but police ask to take it slow if you come across any runners. Everything goes back to normal after the race.
