Hot Pursuit

 (also called Steeple Chase or Snake in the Grass) is a recurring challenge in Survivor.

Rules
While harnessed together, the two tribes will circle around an oval course (either in shallow water or on land) while carrying a twenty-pound backpack each (or similar heavy load). Players can drop out of the challenge at will, but they must give their weight to a tribemate before unclipping themselves from the rope. The first tribe to catch the opponent and touch one of their members wins.

History
The challenge was first used in. Janu Tornell and Jenn Lyon sat out of the challenge for Koror. Jeff Wilson quickly opted out of the challenge because of a injury he sustained the night before. Caryn Groedel was unable to keep it and give her weight Tom Westman. Willard Smith quickly followed. Then Kim Mullen and Angie Jakusz opts out of the challenge. Katie Gallagher leaves the game. Exhausted, Coby Archa opted out. James Miller is the last person to opt out the challenge. Eventually, Koror managed to catch the exhausted Ulong tribe to win immunity.

The challenge reappeared again in . In this version, the tribe that tackles the opposing tribe wins. Both tribes started equally. Eventually the Aitutaki tribe had all their women aside from Jessica Smith drop out at once, strategically handing each of their bags to a man. In spite of this, the physically stronger men of Raro was able to exhaust the men of Aitu. Rebecca opted out when the Aitu tribe was weakened. Yul Kwon tried to defend the tribe, but J.P. Calderon grabbed and pushed down Cao Boi Bui, giving victory to the new Rarotonga tribe.

In, the challenge was adapted to be played on land. The course comprised of a dirt track, and instead of 20-pound sandbags assigned to each player, the tribe was required to carry a single, heavy snake. Corinne Kaplan sat out for the Kota tribe. The Fang tribe struggled, as most of its members dropped out, leaving Matty Whitmore and Ace Gordon to pick up the weight. Kota was much stronger, and Susie Smith's choice to drop out only made them faster. Kota won easily and got coffee, tea, and pastries as a reward.

The challenge moved back to its original design in. Brenda Lowe sat out for Gota, acting as a cheerleader. Gota won the Reward Challenge, as Bikal's strategy of walking for most of the challenge in an attempt to tire out the other tribe failed miserably.

Trivia

 * Ironically, when this challenge was originally used in Palau, the order of which the members of Ulong dropped out (Jeff, Kim, Angie, and James) was the order they were eliminated in.
 * The last women present in the challenge on Palau (Stephenie LaGrossa and Katie Gallagher) became the highest rank women of their tribes.
 * Corinne Kaplan is the only person to be present for this challenge twice.
 * Although in Gabon she did not compete in the challenge since her tribe, Kota, had one extra member and Corinne was chosen to sit out of the challenge.
 * Every tribe that has won this challenge has had an odd number of people on their tribe.
