So yesterday's ride was a semi-epic 80 miler heading north. I chose to ride to the starting point and back home, which made it a century. There were 8 riders total, which TBH is a little more than I prefer these days (I prefer 3-5) but they are all guys I know and have ridden with, and not promiscuous cyclists which is what matters in the days of COVID19. Luckily we are all roughly at the same level and experience, so we rode in a reasonably organized manner. There were some punchy climbs and the testosterone flowing meant that some sections were quite spirited.
After the ride I was totally wiped out, I kinda felt bad for mrs datlas as I was pretty useless for the rest of the day. We had a porch visit from daughter #1 and I got take-out Japanese food which made mrs datlas quite happy and made up for my overall uselessness.
Today's ride was a shorter, easy paced ride. I left early and was home by 10AM. We just went on a fun hike in nearby Valley Forge.
It looks like the birthday boy gets the top spot on the leaderboard. It couldn't happen to a nicer guy.

Hey MoAlpha I have a muscle cramp issue. It's probably a variation of the usual muscle over-exertion cramps, but these cramps have been having a delayed onset.
Typical history is I go on a long, hard ride (like yesterday), but don't cramp on the ride. I come home and rest for an hour or two...at which point ANY minor muscle movement of lower extremities causes severe muscle cramps. This happened yesterday and was VERY unpleasant and it lasted for at least a few hours. Involved mostly quads/hamstrings/calf/flexor hallucis longus (big toe goes up with severe pain in side of calf). I don't know if there is much to do other than stretch and accept it, but any ideas on the pathophysiology and more importantly, treatment for these?

Three miles long, twelve feet wide, cyclists and rollerbladers/ rollerskaters only. Yes, it is the only one of its kind in the country. Do note that it's actually not really any better than the MUP, because there are kids on tiny bikes, people on mountain bikes and hybrids and townies. However, it's another option, and I can ride there from my door.

Well boys and girls, the sink job is finally finished (it was hard work for most of the week), I had a rest day yesterday and a lovely ride this morning. I returned with at least as much energy as I stated with. That's because I got going early while it was still cool out. I would like to do this same route every other day, until I feel up to doing it every day, and expanding into longer rides. I would appreciate a nudge if you see me slipping up. Thank you

According to the prevailing theory, the cause is hyperactivity of the muscle stretch reflex, which, as you may remember, goes from the muscle spindles (muscle length receptors) to the spinal segment via the 1a afferents, which excite the alpha motoneurons back to the same muscle monosynaptically, causing muscle shortening, as in the classic tendon reflexes we test in the clinic. However, in the fatigued state, hyperexcitability in somewhere in the afferent side of the loop can send the muscle into spasm in response to a minor stimulus.
There is an opposing system composed of the Golgi tendon organs (contraction force detectors) which inhibit the spinal motoneurons via the 1b afferents and an inhibitory interneuron. This is the system we recruit by stretching. I believe there is also evidence that it is under-active in the exercise-fatigued state.
Why this happens I don’t think anyone knows. However, there are fairly good cross sectional studies looking at serum chemistry in athletes after hard events and there are no correlations with cramping. This doesn’t rule out helpful pharmacological effects of stuff like Mg++, which may be helpful in nocturnal cramping unrelated to exercise, but that may have a different mechanism.
That’s all what I can tell you, but it’s a cool area and I was a board certified clinical neurophysiologist in my yoot, so I’ll keep looking into it.

Don't think I'll get in a ride today.

I have exactly the same thing. In fact, last night I rolled over into a huge hamstring spasm which I somehow managed to stretch and will into subsiding.

Normally, my ride would go from the 263 past the 517, and go down into the 173, 163,170,174 cluster and back.

When I was an actual yoot back in HS doing track, I'd get these random Charlie-horses in my calves. It was never actually during or after a workout; I would be literally lying on the couch reading a book like a nerd, feel a twinge in my calf, and then after exactly enough time to think "oh crap" it would lock and feel like it was coiling in on itself for a minute and then take days to open back up. Hasn't happened in forever though.
What I get now are back-of-the-thigh cramps, only after long (for me) rides. Kneel down to pet the little dog and WHAM!
