About 4.3 miles, which isn't far compared to most people, & only has 2 hills.
It can be the grounds at work that are the most dangerous section, as there's lots of distracted pedestrians/drivers & 'blue lights' around (a local Hospital)
Average ride is about 14 minutes, dependant on traffic-lights.
Running the same route, barring a slight diversion, through a pedestrianised area, takes me an average time of 29 minutes (27:20 - 27:30 on a good day)
So, I'm not sure if I ride slow, or run fast???
