Did the Half Marathon in 2020
Everything about this Half was incredibly well organised. From the communication emails in the weeks leading up to the race, to the start waves organisation, drinks stations layout and finish area. It's definitely not cheap, but it's worth every penny. You get a fully road closed half marathon that starts and ends in the same place, has no loops/laps and great crowds. There are a few areas where the course narrows to the point that it makes it tricky to overtake (especially at the start where there waves were 1,000 people). I started towards the back of the first wave and spent the first few km's trying to overtake people before getting into a good rhythm. Particular highlights were through Kings College, Grantchester, and the final few km's through Cambridge town centre where the crowds were incredible.
Did the Half Marathon in 2019
Potential PB course but given time of year (first weekend in March) cant rely on the weather. Well marshalled and good course atmosphere. Bit on the pricey side though.
Did the Half Marathon in 2019
Fast flat course. Some iconic views of Cambridge, some long sections of boring main roads but traffic free and lots of supporters. I loved the option of gels at the water stations so I didn't have to carry my own. It was also a nice touch to put names on the race numbers. I thought this was a bit of a gimmick at first but it actually made a big difference having spectators shout my name as I ran around the course. Only criticism - I would have preferred a banana to a beer at the finish (even if it was alcohol free)!

More toilets needed but great course and finishing bag
Did the Half Marathon in 2016
This is a nice, flat course. There are quite big sections without any spectators, but once you get to town it's great!
