<human>: Can you provide a brief overview of the text?

Alright, Saturday was my first race outside of cross country(first and last year doing the sport) which was a run across the [Mackinac Bridge](en.wikipedia.com/wiki/Mackinac_Bridge). Being my first race on my own I sort if winged it with my dynamic stretches to get warmed up. I finally started the race(it was a staggered start and we were timed with rfid chips in our bibs and started whenever we felt like crossing the start line) at 7:42am and it felt good, kept my pace at what felt like my regular longer distance pace at around ~8:30 if not a little faster (Wish that number was much lower, but I started nowhere close to that as I'm still a beginner) and finished before the clock hit 8:25 at the finish line... But  my official time when it was posted on the board came out to be closer to 45 minutes than anything else. Is this normal? I know there is nothing I can do about it and only did it for fun but I cant help but feel a little annoyed about it.
<bot>: Ran my first race but the timings were off by at least a minute or two from what the race clocks were saying at the start and finish lines. Is this normal?
