While the forecast may look chilly and rainy, there are some things you can do to prepare yourself to run your best race on Sunday.
Meteorologist Cecily Tynan has posted some tips on how runners should dress for the Broad Street Run on her Facebook page.
On Friday, runners were picking up their race bibs, packets and t-shirts and some were doing their best to calm pre-race jitters.
Others are watching the forecast. But since we can't control the weather, experts suggest to focus on what you can control.
Justin Shaginaw and Dr. Todd McGrath from the Aria 3B Orthopaedic Institute say by now training should be over.
On Saturday what's recommended for activity depends on your level of experience
"If you're a novice, maybe just go for a walk. If experienced, a light run 2-3 miles to get legs ready for the next day," said Shaginaw.
Over the weekend stay hydrated, but come Sunday morning be careful not to over-hydrate.
"You don't need to drink a gallon of water. A normal glass of water or maybe an electrolyte drink to sip on walking around the starting area," said Dr. McGrath.
And if you find yourself a little unprepared this year, then lower your expectations, take it slow and listen to your body.
As for running gear, if you bought fancy new running clothes, save them for another day.
"Don't switch shoes especially, no inserts keep same running clothes because one little thing can really set you up for a problem," said Shaginaw.
Good luck to all the runners!
