Just in time for the races at Cycle Vision, Roelf completed the last item on the racing hood: the visor of polycarbonate, heated in an oven and pressed in a mold. This visor that can be pushed up or down to regulate the airflow makes an enormous difference to the racing hood I had before, that had a fixed visor right in front of my face. There was no way I could regulate the airflow other than to throw it off.
Now to the praktice. It was about 29degrC. at the racetrack during the Three Hour Race. Would I survive under the hood or throw it in a ditch after a few laps, because it'd get too hot. I was amazed to find that it was actually pretty cool. The airflow went right to my forehead, cooling my head. That was certainly neccessary because the track is a bit narrow for so many racers and spectacular corners. Some were tight at the end and the chicane was tricky, but I found that none of them would have to be slower than 40km/h. That chicane right after the start was very nice. After a few laps I felt confident enough to fully unload one wheel of the Mango and let it fly over the grass in the first corner and to speed up when coming out of the second corner while the unloaded wheel bumped slightly up and down on the pavement because of my hard pedalling to get up to speed again. My Garmin Edge800 was very helpful to determine the maximum approaching speed towards the corners and when it was time to start pedalling again. The Edge also has a thermometer. I didn't look at those digits during the race but in hindsight it is nice to see how warm it gets under the hood, standing still in the burning sun and how much it cools down when travelling some 44km/h on average. The temperature even got lower than the outside temperature. I think, especially because I had no sun burning on a helmet, that I was even cooler than the lowracer riders.
