While most of the focus of the long Fourth of July weekend will be on this evening’s fireworks displays across the Charleston area, plenty of other activities are available before and after those shows.

Granted, unless you read last week’s column or are reading this column online or got up really early Thursday, two trail runs kick off the day.

The seventh July 4th Cross Country Run starts at 8 a.m. Thursday at Trophy Lakes on Johns Island. The cost is $25. See www.theextramileinc.com.

Three rivers away will be another trail run, the inaugural Firecracker 4-Miler at 8:30 a.m., with a kids’ mile fun run at 9:15 a.m. at Laurel Hill Plantation in Mount Pleasant. The late fee is $35 for the 4-miler and $20 for the kids run. See www.timinginc.com/firecracker4miler.html.

Head to James Island

The Charleston County Park and Recreation Commission is offering an array of outsdoorsy adventure activities after the Fourth, most at James Island County Park.

Among them is an American Canoe Association certification course for stand-up paddleboard instruction from 8:30 a.m.-6 p.m. Friday through Sunday at James Island County Park. The fee is $275-$300. www.americancanoe.org

PRC continues its Friday “Challenge Course Open Day” for people to try out its high challenge course at James Island County Park without having to book a full group to do so.

The event will be 3-7 p.m. and does not require advance registration. The cost is $10-$12.

It is for ages 10 and up, though chaperons are required for ages 10-17.

On Saturday, an Early Morning Bird Walk at Caw Caw in Ravenel will be held 8:30-11:30 a.m. Pre-registration is encouraged, but walk-ins are welcome. Cost is $5. Call 795-4386.

Also Saturday is “Climbing 101,” which introduces newbies to the world of climbing with basic instruction on gear, knots, technique and how to belay. It will be 9 a.m.-noon at James Island County Park. The cost is $20-$24.

Instructors also will be giving an introductory course on an emerging activity, slacklining, from 12:30-1:30 p.m. on Saturday at James Island County Park’s new slackline park. The fee is $10-$12.

For competitive types, a new Stand-Up Paddleboard One Design Race Series will be 5:30-6:30 p.m. Saturday at James Island County Park. The cool thing about the series is that all competitors use the same board design and gear, provided by PRC, for this friendly contest for ages 16 and up.

The cost is $5-$6.

Triathlon No. 3

The third of five triathlons in the 23rd annual Charleston Sprint Triathlon Series will start at 7:15 a.m. Sunday at James Island County Park.

The triathlon features a 600-yard freshwater swim in the lake at James Island County Park, continues with a 12-mile bike ride through the park and out and back on Riverland Drive, and finishes with a flat 5K run.

But triathletes and others can get limbered up on the day before, 5:45-6:45 p.m. Saturday, as part of CSTS’s first ever free yoga event, taught by Holy Cow Yoga instructor Erin Levesque.

Sunday’s triathlon will be the last chance for any triathlete who didn’t participate in the first two triathlons to be qualified for the series championship races. Participants have to be in at least three of the five races for open and age group division championships.

Other dates for the series are July 28 and the championship race, featuring double points, Aug. 11.

Fees start at $55 per race.
