A local competition drew athletes from across South Carolina. The report behind it is thin, but the details that survived are the ones that matter.

Elite distance runners carry about 79 percent slow-twitch fibers versus 58 percent in untrained men, and sprinters flip the ratio. But two marathoners with 50 and 98 percent slow-twitch fibers ran the same time, so fiber type opens doors rather than crowning winners.

A first group fitness class runs a warm-up, a main block, and a cool-down with an instructor cueing every move. Research finds small gains over solo training and a real role for confidence.

A fixed eight-station race that mixes running and functional work is chasing Olympic status. Here is what the format actually asks of your body.

Watches and rings derive heart rate variability from the pulse wave using photoplethysmography, while chest straps read the heart's electrical signal. Studies show the methods agree at rest, with error bars that widen under strain and noise.

Time off does not erase your training. What detraining research reveals about muscle memory, movement skills the brain keeps, and why regaining fitness beats starting over.

Winning the title is the hard part. Moving a million people through a downtown safely is the second hard part.

Box scores tell you what happened. Advanced numbers tell you why — if you know which ones to trust.
