I was on a Costa Blanca cycling holiday once when the daily ride was cancelled due to dangerously strong winds. I decided to ignore the warnings and went out with a mate. The wind really was nightmarish and we were struggling to ride up to the tunnels leading from Benidorm to above Calpe. As soon as I got to the start of the first tunnel, I hit a wall of wind and was simply unable to ride any further forwards. I was standing on the pedals in a 39/29 gear and using all of my strength but could not move. My legs soon gave way and I was blown off the back of the bike, which took off and headed towards the Armco barrier and the gorge below. I lunged for the bike and managed to pull it back down onto the road ...
At that point, I thought "
Nah ..."!
We turned and headed back with an amazing tailwind but I was unable to pedal fast enough in my 53/13 top gear. I managed to spin up to 120 rpm which corresponded to 40 mph but then gave up and was doing well over 40 mph freewheeling! (It is a slightly downhill stretch of road.)
When we got back into town, wheelie bins were tumbling past us down the street ...
THAT is definitely too windy to ride in!
