Yes, this year’s 3 Down 300km Audax is running on Saturday 6th April. Starting from Chalfont St Peters, you take on the Chilterns, a bit of the Berkshire Downs, the Hampshire Downs. With the ups mainly over, it’s down the Test Valley (flat and scenic) and over to the far side of the New Forest. And then back again.
