Nice start and here is some info I found about times:
How long does it take? That depends ... my first Grind took 90 minutes, and that's what I tell first-timers to expect. I've taken quite a few people on their first Grind and the times have varied from 51 minutes to 105 minutes. Every person that I know who does the Grind regularly times themselves. I keep a record of every Grind that I've done since May 1, 2004. My personal best is 41:07, but on an average day I'm happy if I do it in under 50 minutes. There are many factors that will influence your time. I don't do very well in the heat; some people don't do well when it's cool, or wet. The second fastest Grind ever was by Jonathan Wyatt of New Zealand, a 3-time World Mountain Running Champion. On June 12, 2004 he went up in 24:22. Sebastian Salas holds both the official record for the Grouse Grind Mountain Run, completing the race in 25:24 in 2009, and the fastest Grind ever in 23:48, done on August 24, 2010. The race starts and finishes in different spots than the actual Grouse Grind, making the course a bit longer.
Congratulations poorboyv6.
My first time was just under 90 minutes as well. On my 6th try within a couple of months, I managed to shave my time to 73 minutes. I still have a ways to go but it's a great workout.
