Cherwell School in north Oxford has the best cycling modal share in the UK. The reason? It has a totally segregated cycle way to link it with student catchment areas.

We are the number one cycling school in the UK! No other school has such a high proportion of students (58.4% and rising) who regularly come to school by bike. Our cycling rate is 20 times the national average. Cherwell has become a benchmark school, a model of good practice in promoting cycling. 15.7% travel by bus and 14.8% walk – adding up to a total of 88.9% who use sustainable means of travel. …

We strongly discourage dropping students off by car, unless there are special circumstances. Given the large volume of bicycles going in and out of the School, there is a risk of an accident – especially at the entrances to South Site and the Rugby Club car park.
