Can any one shed any light on what would be competitive numbers in the 100kg class UK , I'm not finding a lot of info online .
It's going to depend on the federation. If things in the UK are anything like here in Australia in a fed that allows wraps you'll need something along the lines of 270/150/280, or anything that'll get you a 700 kg total.
For what it's worth, it doesn't matter. If you base your goals on what the other guys are doing you're always going to be on the back foot. Just focus on improving your own total steadily.
Thanks for the reply I found some stats from recent comps here in UK and quite close to what you have said.
