Not sure if this is the same thing or not but here goes. Years ago I use to be into long distance cycling (pedal bike), and averaged about 60 to 80 km a day six days a week. I noticed that after pedaling for that long without resting, I would have a hard time adapting to walking on the ground. I thought it was just a matter of using different leg muscles or something like that. Could have been a matter of sitting in the bike saddle and pinching a nerve or a circulation issue as mentioned with a climbing saddle. But I was never dizzy. Always had lots of carbs and water with me! HC
