Ruapuna drag racer Craig Smith killed after parachute deployment caused crash at 250km/h, coroner finds

Smith’s 1967 Ford Cortina veered off the Ruapuna Raceway track at nearly 250km/h, leading to a fata…

Wind plays a major role in cycling, since aerodynamic drag is the greatest force hampering a cyclist. In road racing, both individual cyclists and teams use tactics that vary based on the wind speed and direction. Crosswinds — when the apparent wind comes from the side in the cyclist’s point of view — are some of the toughest conditions to deal with. In races, groups will often form echelons to minimize the group’s overall effort in a crosswind. Alternatively, racers looking to tire their competitors out will position themselves on the road so that the rider behind them gets little to no shelter from the wind; this is known as guttering an opponent.

In this study, researchers put a lone cyclist in a wind tunnel and measured the effects of crosswind from a pure headwind to a pure tailwind and every possible angle in between. From that variation, they were able to mathematically model the aerodynamic effects of crosswind on a cyclist from every angle. With rolling resistance (a cyclist’s second largest opposing force) included, they found relatively few conditions where a crosswind actually helped a cyclist. Most of the time — as any cyclist can tell you — hiding from the wind is beneficial. (Image credit: J. Dylag; research credit: C. Clanet et al.)

Today's #kickbike #ride was the longest one I've done in the last few months - 39.9km. I had 10 kph #headwinds and #crosswinds all the way, and still averaged 15kph. Overall, I'm pretty pleased with the ride.
