For those of us who prefer to exercise outdoors in the late afternoon or commute via bike, this is a challenging time of year.

With the end of daylight saving time two weekends ago and the shorter days between now and the winter solstice on Dec. 21, most of us will increasingly be challenged by perils of darkness.

It’s not only time to pay more attention to cars, potholes and uneven sidewalks, but to take account of your protective gear: lights, reflective clothing and reflectors.

Fortunately, as the fitness culture grows in the U.S. and throughout the world, manufacturers are coming up with some nifty, and inexpensive, gadgets.

Last week, I purchased two lights, one white for the front of my bike and a red one for the back, that have a simple rubber clip that make them easy to move. No screwdrivers needed.

Local running and bike stores are well-stocked with this stuff and promoting November as National Running Safety Month. And while it’s certainly designed to generate sales, isn’t your life worth a couple of $12 lights?

Glow Run

Already this month, Fleet Feet Sports in Mount Pleasant and Pacers & Pints has held a group run featuring an array of lighting and reflective wear.

The Foot Store in Mount Pleasant will hold a similar event (minus the pints) called Let’s Glow for a Run! from 6:30-9 p.m. Thursday at the store, 1909 U.S. Highway 17.

The event includes a four-mile run, a two-mile run and a two-mile walk. It’s free, but call 849-1108 to sign up.

Project Mud

If you haven’t had your fill of mud runs in 2013 yet, you’re in luck.

Project Mud, one of several franchised, national mud runs, returns to the Charleston Tea Plantation on Wadmalaw Island on Saturday.

In trying to find out more, I called and emailed the director, but got no response.

So, turning to the website for the 5K adventure race, which starts at 9:30 a.m., says this: “18+ signature obstacles will challenge participants of all athletic abilities.” The site also says the event is hosting a 1K kids run for ages 13 and under.

The fees are $85 Thursday and Friday, and $95 Saturday. The kids run fees are $15 in advance and $25 the day of. A portion of the proceeds will go to the Medical University of South Carolina’s Children’s Hospital.

Inversion workshop

The most challenging aspect of yoga for many novices is inversions, holding headstands and handstands.

Jivamukti Yoga Charleston is holding a workshop on inversions from 1:30-3:30 p.m. Saturday at the Mount Pleasant studio at 320 W. Coleman Blvd.

Jeffrey Cohen, who will be leading the workshop with assistance from Cortney Ostrosky, says the workshop is “not for fancy moves, show-off chops or above-average acrobatics. This workshop is for everyone who wants to stand on their head because everybody can.”

The fee for the workshop is $30.
