The Blazin’ activity revolves around your Super Sprint power and has you running through a series of checkpoints within a time limit. The catch is that the timer will continuously run unless you collect the little green orbs, which will stop the timer and also increase your speed a bit. While this might seem like it’s easy, there’s one single obstacle, which are the firewalls.
These firewalls, which are red, will deduct from your timer should you hit them, so you need to always be on the lookout while sprinting. Note that a few curveballs will be thrown in from time to time, like the checkpoints being on top or on the sides of buildings, but nothing that should make it too difficult. Arrows will point the way for you, with those pointing upwards meaning you should jump.
