Last night I had the best tailwind I ever experienced (or remember) a strong 30-40 kmh tailwind perfeclty oriented from the north east, which is rare in my area, the wind is usualy coming from the west (north or South) I did my 27.4 kms commute in about 50 min. without much effort.
This morning the wind was still from the north east but was at 5-8 kmh so the ride in was not to bad
