As suggested by the name, a half marathon is half of a Marathon (a 42 km running event). A Half marathon is therefore, approximately a 21 km road running event. While few countries like US have been early adopters of such fitness events; marathons, half marathons and other running events have also gained visible popularity all over India in the last 5 years. While the number of participants has increased over time, the number of participants doesn’t necessarily mean number of finishers.

From the time organisers open registrations for their running event, till the completion of the event, there are three types of participants’ categories – the ones who register, the ones who participate, and the ones who finish. In this brief report, we will focus on and analyse the number of finishers in half marathons in India.
