Why do people sign up for Pamplona’s running of the bulls?

Runners from all over the world come to Pamplona to match their wits with half-tonne bulls in this iconic, and dangerous, festival.

Spain’s week-long running of the bulls festival has kicked off in Pamplona.

People are injured every year – sometimes even killed – as 500-kg bulls chase them through the cobbled streets.

So why on earth would someone sign up for this?
