Heavy localized showers in various parts of the Ottawa region probably scared away some of tonight's potential entrants, however the conditions remained completely dry on the Rockliffe Parkway. The strength of the wind must also have been quite variable in different local regions - in particular the Environment Canada values given above were certainly not what we faced for the time trial! The weather sock was horizontal, and the last 5 kilometers were very tough. This was really not a night for personal bests, yet nine still managed to improve upon their previous DB 15km bests. Natasha Elliott, the fastest woman who was in this class, reported flying out at speeds sometimes up to 52km/hr, and said that she knew that she'd have a good time since she had no problem remaining above 35km/h on the way back. Noting that it takes 8:34 to go 5km at 35km/h, this would mean that if 35km/h was her average speed for that 5km, she would have to have done the first 10km in 1337 (43.53km/h which would correspond to a 20:41 15km TT at constant speed) in order to finish in 22:16.
