For this race, SHADE (shaderoutes.com) computes the real shade along the official course (trees, terrain, buildings) and the felt temperature, in degrees, at every checkpoint, at the time you will be there at your own pace. While the race is more than two weeks away, the weather used is the ten-year normal for the same date (ERA5 reanalysis): it is not a forecast. Free, no account.
