|Trophy: Kerwan Gladiator|
|Complete the fitness course in 70 seconds|
Complete fitness course is a mission in Ratchet & Clank taking place in Aleero City on planet Kerwan. Brax Lectrus assigned Ratchet and Clank this mission to complete Ratchet's training to become a Galactic Ranger.
Completing the fitness course in under 70 seconds unlocks the trophy Kerwan Gladiator.
This mission requires you to traverse two floating islands containing an obstacle course, though traversing it quickly in under 70 seconds unlocks a trophy, so try to finish it fast. Use the Helipack's boost and stretch jumps often, and avoid all crates and breakables to finish it quickly.
On the first island, use the Helipack to boost jump up twice to reach the top of the blocks and then reach a jump slot in the wall in front. Here, wall jump upwards, then head to the right, and wall jump up again, to reach the top of the first island, known as the "Summit of Justice". Use the versa-targets to swing forward to the next floating island.
On the next island, the "Tower of Power", you must jump across the platforms, though many shift position. Jump through the platforms, waiting for some to appear in the right position (though a few can be boost jumped across with the Helipack) before you reach the jump slot, as the walls shift in and out. As they shift out, wall jump upwards, then traverse the next set of moving platforms and wall jumps to reach the top of the tower. Finally, from the orange ledge at the top, boost jump across and glide down to the final island, where you will receive a gold bolt and complete the mission.
After this fitness course, take the flying taxi by jumping inside and pressing , allowing you to progress on with the story. Qwark will give you a new ship, a class-g Star Jumper, and assign you the mission "Find the top secret Blarg research project" in the Blarg Tactical Research Station in Nebula G34. However, before you travel to Nebula G34, first complete the mission "Search the sewers" on Rilgar, as the Trespasser is required in Nebula G34. If Rilgar is not yet unlocked, complete "Help Skidd get to his ship" and "Find Skidd's Agent" on Aridia first.
