In the final moments of a ramp test just before I pop, I suddenly feel pins and needles across my legs. Its very sudden and very sharp and very uncomfortable. Once this happens, I have about 1 to 3 seconds before I quit.
Does anyone know what this sensation? Is it lack of oxygen at the muscles? Is it carbon dioxide build up? Is it death approaching? Probably death approaching.
It feels so scary! I wonder if from a muscle perspective I have more in the tank but once I feel this sensation some sort of survival switch is flipped and I am shutting down. If I were an old school Windows operating system it would be akin to a kernel panic followed by blue screen.
Once, while going for a KOM on a short climb, I got this feeling so badly that my vision blurred and I felt dull headed for 30 minutes afterword. Had to ride straight home after, and I stopped trying for KOMs after that.
Never in my legs but my I get a loss of feeling and the painful tingles in my hands and fingers. Not excruciating pain but certainly painful. I can hold out for another 1-2 minutes most of the time from the first sensation until I am done and it progressively gets worse as I continue to dig in. Happens on ramp test but has also happened on other rides where I am on my limit. I think I am just getting used to it happening once or twice a month.
