EXCLUSIVEBig day, big hair! Behind the scenes with Fox News anchor Martha MacCallum as she reveals the secrets of her election night preparation

Fox News anchor Martha MacCallum has been covering elections for decades — shes well aware that Tuesday is likely going to be a very long night.

I will be working from morning through night tomorrow, she exclusively told DailyMail.com, as MacCallum, 60, revealed how she prepared for 12-straight hours of election coverage.

Best way to focus, lots of water, no sugar, a workout in the am, she revealed.

MacCallum has been with Fox News channel for 20 years and is currently executive editor and anchor of The Story with Martha MacCallum, which airs every weekday at 3pm eastern time.

On Tuesday, the veteran journalist takes on a slightly different role as the co-anchor of FOX News Channels Democracy 2024 election coverage.

Preparation for the marathon coverage at the networks headquarters in New York City began long before she sat down besides co-anchor Bret Baier.

The previous weekend was a working weekend for MacCallum, consumed by editorial meetings, rehearsals in the new and specially-designed Fox News Election studio.

Big day calls for big hair. Daniela and Michelle, who took this photo, are my amazing hair and make-up team, and boy am I lucky to have them! MacCallum captioned this photo.

On Saturday, MacCallum and her co-hosts kicked tires on the new set, learning how all the new election technology functioned.

Then on Sunday, she hosted a special edition of The Story on Sunday and a meeting with Baier to talk strategy.

In between work, MacCallum managed to fit in a paddleball session with friends, saying exercise is one of the keys to de-stressing and staying focused. 

Happy we squeezed in some paddle on this nice Fall evening. Love being outside. Great election de-stressor, said MacCallum

For the actual night, she says diet and rest are crucial. Her go-to coffee order is black with collagen creamer (for an extra boost of protein).

In general, when she is rushing between engagements, she drinks electrolyte drinks and opts for protein bars or a yogurt with granola.

In contrast to her professional polished on-air appearance, MacCallum is happy to keep it casual off-air, wearing corduroys, vintage J. Crew vest and Loro Piana shoes. 

But when its go-time, she has a whole team to help her get ready. 

Big days call for big hair, MacCallum joked. 

Boy am I lucky to have them, she gushed about her glam squad.
