I've been riding for a year now, cruising along at around 22 - 24 km/h on my hybrid, by cruising, I mean putting some effort into it. Yesterday, I ran into a wicked head wind, that slowed me down to 11km/h. At this point, I pushed hard, but could not top 11km/h.

I wasn't in the most aero dynamical position, but man, I thought that perhaps the head wind might stop my forward progress. It was an amazing, yet a slightly scary sensation,

How strong a head wind or any kind wind have you encountered?
