Weird recent experience (injury oriented).

I had that happen with my ankle once.  Was so stiff and painful I couldn't move it one morning.  Felt like a catch in it.  I HAD to play a basketball game that night and could barley walk.  I hobbled around for a half and early in the 2nd half I stepped laterally to get in the path of a pass and the whole gym heard my ankle pop.  All of a sudden I was pain free and had full range of motion.  I went from cripple to speed demon in one step.  Never happened again.  Weirdness

"Are you running 8:20 pace in 105 degree weather?  It's only getting to 100 here in Dallas and it kills me."

I am, but since it is so dry here it isn't really all that hot.

I've had it wear I have a pain in the back of my knee and once I get it to crack it stops hurting.

BTW my cats talk...I just can't understand them

This. Every once in a while I get this. Most commonly I have it happen in my hip, as when doing assisted butterfly stretches I had my partner slip and fall on my knees during the stretch. So now, I occasionally have to point my leg/knee straight out to the side, then lift "up and over" to the front to realign a tendon.

Very rarely will I get this in the foot, but it's happened there too a couple times.

Sounds like some kind of an impingement on nerve--curious, did your foot swell or bruise like there was anything broken or torn?

Whatever popped was probably popping back into place and therefore relieved the pressure on the nerve.

I had a cervical disc slip a couple/three years back and ever since then, once in a while, I'll get horrendous pain going down my shoulder blade and arm. If I can crack my neck just the right way, sometimes it clears up instantly! Sometimes not and it takes a couple days of icing, neck extension and self-traction for it to be relieved

Bah. You're just a stud. I went for 8 in 115, and managed 8:25, wasn't too bad but I definitely was aggressive on fluids/cooling once I got home.

Wouldn't mind seeing a review of coolwings, et. al. at some point as well, Tom.

I disagree.  105 is hot, be it Tucson or Dallas.  That being said, I'd rather be in 105 and in Tucson then in Dallas and it be 90 and 80+% humidity (I like to harass my friends when it gets to 25% humidity here, whining and all that).  The dry heat is easier to manage and all in all very tolerable.  You can actually breath.  But, if your not careful you can do plenty of damage to yourself in these temps. 

Well, it's contextual.

I've raced in the Sahara in northern Africa in the 145 mile ultra distance running race Marathon des Sables and in the Jordan Telecom Desert Cup, a 107 mile running race near the Jordanian Iraqi border. It crosses a mountain pass that sperates Iraq and Jordan. During the day it is over 120 degrees. At night is goes down to 35 degrees. I also did the Raid Gauloises in Vietnam, the longest adventure race in history. Vietnam is hot.

I'm OK in the heat so 105-110 is warm, but its not undoable. Once you take the humidity out of the equation (the humidity on these runs has been 7 and 8% according to weather.com) it isn't bad. I commute to and from work on the bike in that too. It's tolerable.

The 120+ degrees in the Sahara for day after day, up to 55 miles of running a day, with a backpack on, that gets your attention.

Here's a link to a story I wrote about it a long time ago:

Sunrise at the Marathon des Sables:

I agree. There was no swelling. It was weird.

I'm glad its over. Not fun.

Several years ago I had a spot right behind the middle of the ball of my foot.  Would ache in the morning, once my foot "warmed up" it would ease off, then it would return about 40 mins into the evening run. 2 weeks into it I was running on a trail and had to land odd, felt a burning in that spot ran on home and it never bothered me again. 

You've been doing this stuff long enough to know that the body does stuff that really makes no sense at that time.   You sit too long and you feel liked you've done a hard 10 miler,  you get 4 hours of sleep and set a pr on your 10 tt loop.  My favorite thing is to go back over the previous week to figure out why x hurts, and then to come up with no answer and  chalk it up to old age.

My knee does the same sort of thing if I lie down/get up wrong.  The mechanism in your foot might have just been out of alignment, and popped back in.  ???

BTW 1:  My cat talks, mostly to my wife.  She swears that Monster (that's kitty's name, given by my DS because of the cat's green eyes) talks to her when he's hungry, and says, "Mom! Mom!"

BTW 2:  You hot weather runners make me feel like a total wuss!  I'm not complaining about our 90F days anymore!
