It is looking like a breezy day on Saturday — much more autumnal than last year's event
On the 100 you'll have to tough it out a bit to Thaxted, although it's very laney and hedged-in, so you won't suffer too much, plus the wind isn't forecast to strengthen until later. And then a tailwind to Balsham.
On the 200 there are some exposed sections on the lanes before/after Framlingham that will feel a bit tough, but once those are out of the way then it's very laney and hedged-in all the way back to Balsham. And you might get a bit of a headwind on final stage as you climb past the prison, but it's not for long.
Everyone will feel it a bit from the side along the straight drop into Fulbourn, and on tired legs it will feel a bit OTT, but it's only a couple of miles and you're almost done by that point.
I'm keeping an eye on it, but at the moment the wind is not forecast to be that strong, a bit gusty in the afternoon, and there are no weather warnings in place.
