To what extent is pi non-repeating? I've been told that pi is an irrational (infinite and non-repeating) number.
But to what extent is it non-repeating?
It obviously repeats individual numbers, and I find it hard to believe that it doesn't repeat 2-3 digit sections eventually.

$\pi$ certainly does repeat 2-3 digit sections eventually. There are only 1,000 different sequences of 3 digits, so there's no way that $\pi$ (or any other number) can avoid repeating some of them. 
In fact, if $\pi$ is a so-called normal number, then every possible 3-digit sequence appears infinitely many times (as does every 10-digit sequence, every 1,000,000-digit sequence, and so on). 
When we say that the decimal expansion of $\pi$ is "non-repeating", what we mean is that $\pi$ never begins to repeat just one sequence of digits over and over forever. In other words, the decimal expansion of $\pi$ can repeat itself; it just can't ever fall into a cycle where it repeats the same thing forever.
