This one is a bit of a faff lads im afraid Train takes a long time but it is direct and still quicker than taking a car You will need to be on the 1000am train from East Croydon, 1031 from Blackfriars, 1040 London St Pancras arriving Cambridge at 1148am. Its then a 3mile uber to ground Wilberforce Road CB3 0EQ We are in white blue white
If you miss this train you will be late
On the way back its the 1655 to kings cross arrives 1819 and then make your way from there
