As we enter the second half of July, a summer lull in outdoor activities is approaching. It’s a time when families squeeze in vacations, or at least head to the mountains, before school resumes; heat and humidity wilts some of the less hardy; and people who plan events avoid it like the plague. But we still have one weekend with a fairly full calendar of events.

Climb for Air

One of the few indoor events that I consider for this column each year is the annual Fight for Air Climb, a stair-climbing event at the North Charleston Coliseum that raises money for the American Lung Association in South Carolina.

The event is in its fourth year, despite the fact that it has drawn about or less than 100 participants in each of the previous three years.

This year’s event will be Saturday morning and feature the “Ultra Climb,” which is all 5,044 steps at the coliseum and “The Climb,” a mere 1,566 steps, as well as the “Firefighter Challenge.” The latter consists of “The Climb” but for firefighters in about 50 pounds of gear (except boots) with the option to compete with air on or air off.

Each event requires a $25 registration fee and minimum fundraising of $100 for The Climb and Firefighter Challenge and $150 for the Ultra Challenge. Online registration closes at 8 p.m. Friday. In-person registration on Saturday starts shortly before each event begins. The Ultra starts at 7 a.m. and The Climb at 8:30 a.m.

Melanie Baker Matthews, ALA program coordinator of the coastal region chapter, says the organization hopes to raise $40,000. The event sponsor is East Shore Athletic Club.

Jammer volleyball

The summer hiatus is prime time for volleyball, and The Windjammer is hosting The Isle of Palms Beach Tournament on Saturday and Sunday. Check-in is at 8:30 a.m. both days.

The tournament is part of the East End Volleyball and Volley America grand prix, which includes events along the East Coast and points toward a national ranking system. So even if you’re not a volleyball player, the level of play at the ‘Jammer will be raised a few bars.

Divisions include junior doubles (girls 18 and under and 16 and under, girls and boys combined, 14 and under and 12 and under) and all adult.

Capers ECOrun

If you haven’t done a Capers Island ECOrun yet, it’s like a little day adventure that doesn’t require a heck of a lot of work, other than running a 10K or 5K on the island’s Boneyard Beach. Capers is mostly wild barrier island, free of cars, pavement and houses.

The umpteenth installment of the ECOrun series is Sunday, with a ferry departure from the Isle of Palms Marina at 9:30 a.m. The cost is $45-$50 and includes the ferry ride, which is always fun. Keep in mind that parking at the marina is $3.

Time to SUP

With the full moon lighting the way Monday, a couple of easy-going stand-up paddleboarding trips are planned.

Half-Moon Outfitters in Mount Pleasant is launching one from the Pitt Street Bridge at 8:30 p.m. The paddle is open to all levels. For those needing a paddleboard, call or email Half-Moon at 881-9472 or mtpleasant@halfmoonoutfitters.com at least 24 hours in advance.

The trip is $5 with your own board or $20 to rent a board.

For those who’d rather kayak, Half-Moon’s Janice Fetter says, “Come on, come on.”
