Ok, kiddo, so you know how when you run with your friends, you can pass a baton to the next person on your team to keep the race going? Well, that's kind of like what the Italy national relays team does at the international athletics championships.
The team is made up of really good runners from Italy who are chosen to compete in these big races against runners from other countries. The races are called relays because each runner on the team takes turns running a part of the race.
Each team is made up of four runners who run different distances. The first runner starts the race and runs as fast as they can for a certain distance, then they pass a baton to the next runner, who runs their part of the race until they pass the baton to the third runner, and so on.
The goal is for the team to run as fast as they can together and beat the other teams. It's kind of like a big game of tag where the Italy team is trying to tag all the other teams before they can tag them.
At the international athletics championships, lots of teams from different countries come to compete in these relay races. Italy is really good at running, so they send some of their best runners to represent the country on the national relay team.
It's a big honor to be chosen to represent Italy, and the runners have to train really hard to make sure they are in their best shape for the races. They practice passing the baton and running together as a team so they can be as fast as possible.
And if the Italy national relay team does really well, they might even win a medal for their country! Does that all make sense to you, kiddo?
