Grand Theft Auto: San Andreas/Chiliad Challenge

Requirements

 * Mission: The Green Sabre
 * Location: Flat area on top of Mount Chiliad

Walkthrough
Get on the mountain bike at the top of the mountain to start the challenge. You can only do this between 7:00 and 18:00.

The challenge is a set of races conducted like any others, with checkpoints and competitors, just on a bike. There are three races, and you have to finish first in each to compete in the next, or to ultimately finish the mission.

Scotch Bonnet Yellow Route
This course winds down the southwest side of the mountain, and ends near the trailer across the street from Angel Pine. If you rode up the mountain this is probably the reverse of the route you took to get there.

After a few times down you will get used to the motions of braking into the hairpin turns and accelerating on the straightaways.

Birdseye Winder
This course starts and ends in the same place as the first one, but winds down the north face and then all the way around counterclockwise. This one's pretty tough because there are many places to fall off course.

The first two turns are the same as in the first race. Then comes a long, nearly straight stretch. Watch for the slight rights; if you are going too fast you will run into the fence which will result in an annoying delay. After that is a big hairpin turn with a cliff on the outside. Use the back brakes to slow down without losing control. After the big turn, watch out for the slight lefts or you will ride right off the mountain.

The next turn is around a scrub of bushes and is protected by a cliff wall. So it's a pretty safe turn; just don't get lost in the bushes and run off the side. The next turn is very tight and very downhill. Keep to the left to be safe, and if you spin out while braking you can recover in the right direction. After this turn don't go crazy with acceleration--there are some "slight" lefts with cliffs on the right and you can fall off.

The next big turn to the right is also dangerous, but you won't be going so fast at this point anyway. Then it's kind of bumpy to the next turn. You can just go straight towards the checkpoint, run off the cliff and land near the checkpoint after the course turns.

Now is a long, somewhat straight stretch where you can let it out and accelerate all you want. But when you emerge from the trees there will be some left turns with guard rails on the right. Hanging up on these guard rails can bring you to a very frustrating abrupt stop, so slow down and/or cut the corner by staying on the hill on the left.

There are two of these left turns with guard rails. The next one has a wooden fence and is a little less treacherous. After this you're nearly home free. There's one more downhill hairpin turn. As you accelerate towards the finish line, take care to stay to the right because there are a few more slight turns that can result in you falling off the cliff.

Cobra Run
This course careens down the woodsy east face of the mountain and features a section on a boardwalk.

Tips
The hardest part of the Chiliad Challenge is not speed; it's staying on the track. At the beginning of the race focus on steering and you will glide right into a high position. Use pedal power to push ahead, but only in the straight sections. Remember holding the pedal button accelerates, and tapping it accelerates faster but with less controllability. Remember gravity is on your side! Use the rear brakes around the hairpin turns.

Avoid the fences and side walls or you can get stopped or turned around. You can use bunny hops and turn in the air to get awy from one of these hangups. Also try to keep away from the competitors because they (by malice or incompetence) can run you off the course.

A Sanchez and Mountain Bike spawn near the trailer at the finish line. That should help you with getting up the mountain. Alternatively, go the San Fierro Airport and take a helicopter.

You can make the trip from the save house in Angel Pine to the top of the mountain in about three minutes. So save your game at the house around 22:00. You restart at 04:00. Leave the house, get in the first car you see, drive to the finish line, and pick up the Sanchez. You should get to the top right around 07:00, then hop on the Mountain Bike and get started. You can probably get two attempts at the race per day.

Rewards
Progress towards 100% Completion.

Miscellaneous
While at the top of the mountain waiting for 07:00 you might find the need to amuse yourself. Here are some ideas:


 * Take pictures of the moon and the sunrise.
 * Push the vans (a Camper and a Journey spawn there) off the side of the moutain.
 * Use the memorial plaque as a ramp and get an insane jump.
 * Take the parachute and try some BASE jumping.
 * Try to shoot down the errant planes.
