Terminology sometimes gets in the way. Especially differing definitions of the same term. I always understood bonk to mean low blood sugar. Only food will fix that. I bonked often in my youth when I was careless about my diet and ate way too much sugary junk. Yup, I was actually tested as hypoglycemic. Better diet and exercise fixed the problem. But once it's happened you never forget the sensation or mistake it for any other type of exhaustion.

Cracking is even less precise, and seems to describe dead legs from lactate buildup, especially on climbs or full gas crits. Sometimes we can recover from that just by reducing effort for a few minutes, pedaling (or running) easily until the body converts it to usable fuel, after which sometimes we get that magical second wind.

But bonk sometimes seems to be used to describe dehydration, dead legs while we feel fine otherwise, etc.

The other day I was chattering with a fellow who's been riding only a year but is much stronger (and younger) than I. He said leg pain sometimes interferes with riding, but there was a language barrier so it wasn't clear what kind of pain he was describing.

I tried to figure out, unsuccessfully, whether the fellow was describing an injury that needed rest and/or treatment, muscle soreness that persisted after every ride, or lactate buildup that's transient and clears up with reduced effort, or a good cooldown ride or trainer spin to clear the legs. We couldn't navigate the language barrier.

I tried to suggest my favorite post-ride trick, a heavy marble rolling pin for my legs, but he thought I was talking about a foam roller. I do use a foam roller on my back and glutes, but the heavy marble rolling pin works much better for the legs, especially overcooked quads. Next best thing to a soigneur or masseur. I seldom have sore leg after rides or leg exercises using that trick.

I also would have suggested a true recovery ride, which varies for everyone. In my area a club hosts a couple of weekend recovery rides, but those are based on the fitness of the demographic: teens to early 30s, pros and serious amateurs. I've tagged along with them a couple of times and their recovery ride pace is my full gas pace. I need a true recovery ride afterward, which for me sometimes means a 12 mph loaf around the neighborhood on my hybrid, checking my heart rate to be sure I'm staying in the recovery zone.

That advice may have gotten through because the fellow nodded, smiled and took off on his own rather than following the club. At least I'm hoping what happened.

As usual, some club MAMIL and MUPpet warrior dismissed it with a "HTFU." It's usually one of those guys who enjoys posting Strava times and speeds faster than he's capable of riding solo, but is good at drafting and never takes a pull. One of those guys who boasts he never wastes time on casual or less than full gas rides. Probably because he doesn't want anyone to see his average solo speed is significantly slower than his club rides. It's usually the guys with decent engines and cardio fitness but 25-50 lbs overweight, who rely on drafting the stronger guys, blowing through intersections to avoid posting a slower Strava time, and complain about pedestrians, joggers and pets on the MUP interfering with their pursuit of a sidewalk KOM.

Take advice from those guys with a generous dose of salts, especially if it includes a sprinkling of fish tales and claims for fitness belied by their 40" waists.
