About Cambridge 5K Races

Several Cambridge 5K races have come and gone. We are lucky to have The Cambridge Half back again this year.

I’ve run several of these races and had a great time.

As runners we need to be good guests and respectful of the people who live in the neighborhoods that we run through.

When only one side of a road is open to runners, we need to let traffic use the other side of the road.

We are guests and we are inconveniencing people so we can have our fun. We also have to keep in mind that most people think we are crazy to be out running in the first place.

I don’t know what the answer is, but there has to be a way to co-exist with the city while we have our fun. If you have ideas on where races could be staged or how we could be less of a nuisance to the citizens of Cambridge, please reply to this blog with your ideas.

Run well my Friends, and see you in Cambridge!
