This cannot be boosted, not that I'm aware of anyway. Pretty straight forward win 5 Gold medals. Doesn't have to be in a row, it's accumulated over your online play. Easiest way I did this was through
"Custom Games" and picked "Track Events".
I just finished boosting this with my older brother Kyzer Sosei by choosing Custom Match>Versus>Table Tennis. It took a couple trys to get a match together but once we did took turns winning .
