I graduated in 2005 and ran a 5:06 1600 at that time. I didn't win any big meets, but in most of the races I ran, I was around 2nd - 4th place out of a dozen or so guys in the race. I wasn't the fastest guy on the team, but I was fast enough to make it onto the varsity 4x1600 "A" squad. Our XC and track teams were average or maybe even a bit above average.
I had an on-off relationship towards running in my 20s, but never gained much weight or gotten really out of shape. The past few months, the introduction of the new "super spikes" sparked my interest in running seriously again, and I wondered what it would be like to relive my competitive running days and race on the track.
So I went to the local college's website, found out that they allowed unattached runners, and noticed that they didn't have any qualifying standards or minimum marks. It wasn't a D1 school or anything of that caliber. Long story short, I ran a 4:40 1500, which is faster than my HS PR if you were to convert that to the equivalent 1600 time. But even though I was in the slowest heat, I only beat two other guys - one guy from an NAIA school, and one other person running unattached.
Now, I'll admit that my memory of HS track and XC is a bit hazy, but I do know that my performance relative to everyone else in that 1500 did not resemble my HS running days. Are most guys really much faster now, or was the meet that I ran in an anomaly? I lost to the main pack by something like 20-30 seconds, and there's no way the spikes made that much of a difference.
