Boys Indoor Records That Are Nearly Impossible To Break

Which indoor records are unbreakable? 

So far, three national records have gone down this indoor season, including the boys 4x4 and 4x2, and the girls 3000m. We could potentially see a few more records, specifically in the girls 600m and 800m from Trenton's (NJ) Athing Mu.  

As we've come to see, some records are more untouchable than others. So we've decided to take a look at the all-time indoor list to see which of the boys records are less likely to be broken in 2019 than others.
