I figured for anyone who wanted to join in on some All Sports runs, here are the current list of strats that we've come up with the help the run. Many others will be able to chime in below, but I figured until someone makes a video like Alaska did, here will be a good start.
I suggest starting with Frisbee Golf, as making the first hole a hole in one is a pretty big save, and something that can easily be reset for.
Frisbee Golf: Classic B- This course is the fastest course by far. Hole 13 will be a Hole-in-One. Hole 14 will be an Albatross, and Hole 15 will be an Eagle. You will want to learn how to Wipeout-throw. For now you can watch any of the top runners (Alaska, Cmdr, Cedrik, Wipeoutjack).
Golf: Classic B- Classic B is quick and is the safer approach over the faster "Classic C". You want a quick birdie on hole 13, eagle on hole 14, and birdie on hole 15. Eagling Hole 15 will save 6 seconds. We call this "ECA, or "Eagle Cutscene Abuse" (Trademarked by Alaska) of skipping the replay for the last hole, but isn't realistic to waste time to go for.
Swordplay Duel- Either using Fumkio or Ryan to duel. Fumkio is all about up and down swings, Ryan is side to side. I would personally say Ryan is faster, as you can three swing him if you are perfect, but for now it will be player preference.
Power Cruising- The fastest strat currently is to play Cavern, which can get you a 52 second time if you are quick. Boost as much as possible, but make sure you are in the water and perferably, when you are about to hit a wave.
Archery- Archery is one of the more relaxing sports. All you have to do is shoot straight at the ground as fast as you can for each one of the twelve shots. One the last shot, you aim at the air to allow for a quicker pause. Currently Beginner is the quickest, but we are playing around with Intermediate potensially being fast as well.
Cycling- TO THE BEACH!!! You must choose the 2nd stage, otherwise you are in for a bad time (quite literally). Remember to do the boosting as much as you can while drafting as much as you can. It's a challenge to get sub 2 minutes on this, but it is what to aim for.
Table Tennis- It is our friend Cole! Alaska has a video showing how to backspin the serve to foil Cole every time. Along with getting to return aces on Cole, that makes this pretty easily. You can also do DTB (Double Table Bounces) to speed up your serves. Watch Cringe_Daisy's BtC: Table Tennis Match record to see how he does it.
Extra Notes by Alaskaxp2: In Table tennis, if you want to use backspin, hold your hand in the direction you want the ball to go, and swing it in a J-shape towards the TV. While you are doing this, your hand should start off facing towards you, but end up facing the TV. This is a strat used ONLY in points where you’re serving. When Cole is serving, try to hit an early shot, directing it as far away from Cole as possible. If you have any questions, ask in the Wii Sports Discord server (in the WSR forums). Thanks!
Canoeing- After almost getting 100m about three times to set this up, you'll just complete the course as fast as possible. After a few attempts, you'll find a rhythm to it. Slow deep paddles, back and forth. Keep both hands on the Wii Remote like an actual paddle. Stuff like having the sensor bar above you and the hands on the top of the wii remote have been known to be helpful.
Basketball- Now is basketball we do a strat called "Jumpless" GhostT does a great job explaining it here - https://www.speedrun.com/wsr/guide/9rxbw
Bowling- This one is easy to say, hard to pull off. Strike the first 9 frames, don't strike the first 10th frame attempt and then angle the bowling ball to land in the gutter as soon as it can. Exit as soon as it lands in the gutter.
Wakeboarding- The only real "autoscroller". You just have to do a Beginner run. Just sit there and relax. Use this as a break inbetween some of the bigger runs. Exit once "Finished" appears.
Skydiving- Once you jump out, immediately dive backward, grab someone, flip around to go head first, and start dropping. This is called "Gwen Skip", and it saves 5-6 seconds if pulled off well. Angle the Wii Remote down to where you are falling the fastest (hint, it isn't straight down, kind of at a 45 I find.) Time stops when you get your picture taken.
Forgot to add this when it was found.
In frisbee golf, if you throw at a slightly downward angle, your frisbee will gain more speed then usual. This hole 1 shows it off pretty well
In the past, runs below a certain threshold could be submitted without video. Now, this system has been removed. All runs require video proof from now on.
