It simply means you are the first person on your relay team to run :D
anchor
The burden of relay refers to the responsibility placed on a relay team's anchor leg runner to bring the baton across the finish line. This runner carries the weight of the team's performance and often faces pressure to secure a win or maintain a lead. It is a critical position in relay races where a team's success can hinge on the performance of the anchor leg runner.
typically a relay has four "legs" or four different runners. Each must finish a specific distance (often one lap around course) before next runner can start. The first runner is the "first leg" of the relay.
That was the 4x100 meter relay at the 1932 Summer Games in Los Angeles. He ran the second leg for the team with Bob Kiesel running first, Hector Dyer running third, and Frank Wykoff running the final leg.
What would happen is the first runner would run half the length of the track and pass it off. Following this, the next leg would pass the baton at the finish line to the third leg. Finally, the third leg would pass it to the fourth leg where the the 2nd leg was orginially.

Each segment of the relay is referred to as a leg.
A baton is the object that is passed between relay runners in a relay race.
at competitive galas, usually 4. occasionally 8. :)
last man
The anchor is the last person on a relay race team. Because it is such a critical position, it is often filled by the team's best runner. The term is used in a similar fashion in other team sports as well, such as league bowling.
