Find out what level bleep test you require for your age. If you can do 1 level better thats as good as it needs to be. Don't try too hard when you first arrive, as improvement is the key (makes the PTIs look good)
The 1 1/2 mile at the fam visit, just decides which PTI group you will be in.
Group 1. Is for racing snakes and fitness freaks so you will work really hard during IOT.
Group 2. Is for the competitve but not so fit, so you will still work really hard.
Group 3. Hear goes the none PC bit, is generally for the couch potatoes and the girls.
Now the logic, they will nearly all pass IOT regardless of fitness, so if you like looking at girls arses and you want to be able to improve, go for a nice steady run on the fam visit.
You aint seen me right!
