First it was mud runs. Then it was color runs. Now, the latest noncompetitive alternative to conventional road races, “glow runs” held at night, arrives in Charleston this weekend with a flurry of events in the coming weeks.

Glow runs are basically runs in the dark often featuring some or all of the following: glow sticks, fluorescent clothing, glowing body paint, black lights and lasers to make all this stuff pop, light shows and even “glowing dancers,” along with music and beer.

Unfortunately, the one this Saturday night, the GoGlow 5K presented by Half-Moon Outfitters, has reached its 950-person cap, unless you’re willing to pony up a Benjamin for a charity bib.

If you are, go to go-greenevents.com/event/id/1048.

If you can’t or won’t, you won’t have to wait long until the next one.

The Charlotte Hayes Glow in the Dark Fun Run will start at 7:30 p.m. (Yeah, I know, it’s not dark until 8:30-ish these days.) May 31 at Woodland High School, 4128 U.S. Highway 78 in Dorchester. Participants are encouraged to don “glow wear.”

Fees are $35 for adults and $15 for kids. The registration deadline is 11:59 p.m. May 30.

And if that’s not convenient or enticing, the Rave Run series, described as a “colorful assault on your senses,” kicks off at 9 p.m. June 8 at the Charleston Harbor Resort and Marina in Mount Pleasant.

The run will be held on the golf cart path of Patriots Point Links.

Two other Rave Runs will be held Aug. 17 and on a date that has yet to be announced.

Like the other kinds of races with no clocks, the Rave Run will cost you for all that entertainment and diversions: nearly $50 for one race and more than $91 for two races.

Teams of four can register for anywhere between $170 and $425.

Memorial Day events

Back to this weekend, three local fitness events have Memorial Day themes.

At 6:30 p.m. Thursday, the Charleston County Park and Recreation Commission continues its efforts to offer active recreation with the Run to Remember 5K at the Mount Pleasant Pier at Memorial Waterfront Park.

The fee is $28 for county residents and $34 for nonresidents. www.ccprc.com

On Monday, CrossFit Discovery on Society Street will feature different workouts of the day 8 a.m.-3 p.m. to honor individual veterans killed in the line of duty.

A schedule and description of each veteran is listed at tinyurl.com/m4fxql8.

Find out more on the Remember the Heroes 2013 event page on Facebook.

Finally, Charleston Community Yoga is dedicating its one and only yoga class on Memorial Day to all who have served in the U.S. military.

The class will be held at 9 a.m. Monday at 815 Savannah Highway in Avondale.

A portion of the $10 fee will be donated to the Wounded Warriors Project.

Run Forrest Run

Meanwhile, the baseball-themed RiverDogs Run Forrest Run 5K at Riley Park (the finish line is home plate) begins at 4 p.m. Saturday.

The fee is $30.
