Easy "Multi-Disciplined" achievement

There are a total of six hobbies and pastimes (Shooting Range, Flight School, Offroad Race, Sea Race, Street Race, and Triathlon) in GTA 5. You only need to get one gold medal for each type of activity to get the "Multi-Disciplined" achievement. All of them become available automatically by completing story missions. The shooting range is probably the hardest to get a gold medal in. You will have to get a certain number of points within a time limit. Shoot quickly and always hit the yellow center area of the targets. In the flight school, you just need to beat a simple time limit in the first tutorial. In races and triathlon, you need to finish first to get a gold medal. Street races become available by completing Hao's side mission. However, the mission requires you to get a gold medal in a street race. Thus, you will not need to complete any further races to get the "Multi-Disciplined" achievement. Note: Hao's side mission only becomes available from 8 p.m. to 5 a.m. while playing as Franklin, and is shown as a question mark on the map. For the other hobbies and pastimes, you can choose any desired character.
