US National Masters 2008 results:
you didn't mention your age, but look at these results for
masters in the 85 kg class... it should give you an idea.
Here's the link to what it takes to qualify for the 2008 Pan-American Masters:
(The homepage has this quote on it: "There are no qualifying totals to enter our Nationals. To be eligible one must be a registered master weightlifter and have competed in a sanctioned weightlifting competition within the past three years.")
I find the real challenge to be finding and getting to a meet, I almost entered
the Tommy Kono last August after I went to the seminar on the day before the meet and chatted with one of the organizers of the meet; his response to my idea
of joining in was that he'd be happy to see me there, no minimum qualification weights would be required, and I could even get away without the official uniform
as long as what I wore met the intent of the singlet. (Alas, family commitment thwarted those plans).
About the only musts are that you join the USA Weightlifting, and that you must be present to compete.
BTW, at 48 years and 94kg, my all-time unjudged garage bests are 57kg SN + 93kg C&J...
...I definitely wouldn't have wow'd anyone at that meet, except maybe myself or my 4 and 7 year-olds. (I rue the day when they aren't so easily cajoled into hero worshipping me)
