How to unlock the A Close Second achievement in LEGO The Incredibles - Definitive Guide
Most of the races are designed with Dash in mind, so you may get this naturally trying to figure out the timing of some of the trickier races (there's one at the fish market that took me several tries). However, if you find you need to farm this, it's a bit more complicated than just waiting at the finish line, as the race will time out after a period of inactivity or a period of not having gone through a race marker.
If you do need to farm this, I recommend the race at the farm at Outer Muiciberg. It's more or less a straight line of ten checkpoints, and you can walk/jog (just hold the left stick about halfway up) through each checkpoint. If you hit a ring about every ten seconds, you'll be set for this trophy and will have ten or fifteen seconds that you can hang out at the finish line waiting for the timer to hit the silver medal time.
There are races in each district in the hub of Municiberg. The easiest race to do this achievement would be on the farm at the Outer Municiberg. It's a straight line of 10 checkpoints. Look at the timer to match up what you need for silver. Slow down if you have to. Be sure not to get gold or bronze for this. Obtaining silver will unlock the achievement.
