I searched and came up with worthless volumes.

I was on the trainer today and my left leg fell asleep. This has never happened before, although last week it began to tingle and I just thought it was the vibrations from the trainer (Cycleops magnetic), but thinking back on it, there may have been other times it was starting to go and I wrote it off as vibrations. I usually ride for about an hour, my seat is about a year old and pretty good (Avenir Chelan) I shift around in the seat to avoid this kind of thing and furthermore I have been on long rides 30-50 miles (outdoors) with no problems.

I have only had the trainer for about a month so perhaps this is just a "side effect" from vibrations?
...any thoughts? (I have good circulation and am quite fit).

Thanks.

Something is probably cutting off cirulation. Do you wear your cycling shorts or something different? Are you sitting more upright than when you are riding outdoors? Are you leaning to one side of the other?

I have cycling shorts, I don't sit more upright and I don't think I lean...but I know there is a slope to the floor in my apartment. Do you think that such a slight slope may pinch just enough to cut off the blood? I dunno, but that is why I am asking...

what part of your leg?

I doubt the slight slope would cause a problem. I changed forks and got a 1cm drop on my top tube without causing that much of a problem. Not sure what else it could be though.

Please define "fell asleep"!

???


It was my foot that fell asleep, that is why I thought it was vibrations, because it was not my entire leg (should have been more clear in the title). I may be lost on this one, I'll see if it continues and then talk to a doctor if need be, I have an appt in three weeks anyway.

Yes, please define. Did you mean you could no longer move your foot? You could no longer feel your foot? Both of the above? Or you have pins and needles in your foot? Is there still sensation on the skin?

"Fell asleep" is a very poor description.

Foot falling asleep sounds like a hot spot on the foot. Any changes in pedals/cleats or shoes?

I am not sure if this will help, I rode the Alpine Loop in utah last early spring before the road opened for traffic. When i headed up to sundance on the backside it was shady and cold. Riding in my shorts (illequipped) My left foot fell asleep during the ascent. When I got up to Aspen Grove the sun was out and it was warming up, my foot came back to life. You might be a little cold, slowing circulation.

I lose one or more of my legs when I get into my TT position for too long (on my road bike). I got Profile Fast Foward seatpost just for TT use, and it has quadrupled the amount of time I can spend in the aero bars before I start to get the tingling. It brought my effective seat tube angle to 79, but that doesn't appear to be quite enough :-/

I've found that it has to do with being bent over too far. If I take 1 minute "breaks" with hands on the bar tops, I won't experience any problems at all.

Recently, before the new seatpost, I also had pinky and ring finger on my right hand go numb and unresponsive along with my legs. Very strange feeling to come flying into a finish and realize you can't get as much rear brake as you planned for.

Anyway, I'd look into raising your hand position and stretching to improve flexibility.

I had the same thing happen to me - just one foot. Try slightly adjusting your saddle height down, the overextension could be cutting off blood supply. Try loosening up your shoes a bit and make sure your bike is level when in the trainer. If your shoes are super tight across the top of your foot, it can cause hot spots and maybe even "sleepy foot". For what it's worth, since I got custom footbeds for my shoes, all foot pains, and sleeping sensations have gone away.

I think this should help with the "definition"...

Thanks GregP, Stormin, and Waterrockets...I'll make some adjustments. I am pretty sure it is either the slight pressure from my left strap (it is tighter) or/and the cold in the appartment. Either way, I'm glad it is not terribly unique.

best.
