It's all about the suds. The national outdoor fun-run phenomenon, Bubble Palooza, makes its way to Long Island for the first time on Saturday.

"It's a run, walk or stroll," says event director Dean Del Prete. "There are no awards. We don't want it to be competitive."

Mostly, it's just messy fun for friends and families, an excuse to get dressed up in tutus or wild outfits and get covered in mounds and mounds of rainbow-colored bubbles.

BEFORE THE RUN

Come early to join the "bubble bash," when machines blow foam of all hues for people to swim, jump and play in as a DJ plays music. "It's magical," says Del Prete. "Kids love it."

The fun takes place a half-hour before the race begins -- the bubble machines are also turned back on at the end, so kids and grown-ups alike can get one last photo-op.

Families and teens are the main participants, says Del Prete.

Ice cream, Italian ices, cotton candy and popcorn, as well as beverages, will be for sale.

RUN WITH THE RAINBOWS

After the opening bash, runners/walkers/strollers follow the 5k path (3.1 miles), where each participant also gets handfuls of brightly colored dust in various colors to throw at each other -- or even on themselves. And even more bubbles.

Part of the fun is getting as wet and colorful as possible. And since there's no competitive aspect, everyone can go at his or her own speed.

Courtney Hunt, 44, of Indianapolis, Indiana, did a Bubble Palooza run with her kids two years ago when the event was in her town.

"It was appropriate for the entire family," Hunt says, noting her four children ranged in age from 5 to 14 at the time. "Even the little one got to experience it."

GOOD TO KNOW

The powder is colored with vegetable dye, Del Prete says, and it may cause discoloration on some clothing. That's why participants get a race T-shirt to wear that, with all its colorings from the event, becomes a tie-dyed-like keepsake of the day. A few good washings should take color out of hair and skin.

But the event is a wet one, so it's a good idea to bring an old towel and maybe even a plastic bag to sit on for the ride home..

"It was so much fun last year, that when it came time I had to sign up again," says Gwen Nelson, 41, of Lake County, Illinois, who participated with her 6-year-old son Jack. "It's nice that it's not really a competition -- unless you say it's one to see who can have the most fun."
