true but if team GB had fielded the best its got in each then youd expect that person to have had the gold, so its in the right ballpark. Thats what the table is ranked on right? I guess its misleading for the silver and bronze totals, indeed.
In most of the team events the home nations teams will presumably be weaker than a combined team, so the Australian team at hockey, netball or bowls should find it easier beating Teams England, Scotland etc separately rather than beating Team GB.
Sonia O'Sullivan was running the Boston marathon the last time I did it. I was behind her for a while and was amazed at how many calls on 'way to go Sonia' etc she was getting - I'd thought the Americans would be too parochial to recognise the former 5,000m world champion. Then as I went past I noticed she had 'Sonia' in big letters on the front of her Thames vest.
PRW, I think that running training may well get you more gains at this stage than shaving time off on the bike or swim. But don't worry about a standalone marathon: some shorter stuff to get your basic speed improved and endurance stuff more focussed on running off the bike.
Standalone marathon can be an indicator of IM run, but only if you've already done one (the marathon) and trained. Training specifically to get your marathon time down isn't the best way to train for an IM run.
GB at the top of the page is a case in point - he's clearly got a lot of basic speed as his parkrun time shows, and he's done the training to run off the bike. His standalone marathon looks out of kilter to that - most sub 17 parkrunners could probably look at something around 2:45 for a marathon, but that might take a lot of specific training that wouldn't help his bike or swim.
Bear in mind that even 'shite' runners (as you describe yourself) can convert well to IM, if they're trained for it. Equally, many faster runners don't convert as well. Pacing the IM leg sensibly is hugely important. As an unfortunate example, I once started the run at Roth needing 3:10 for sub 10, and having run 2:35 a few months earlier I was confident I'd be OK. Too confident as it turned out - first 10k at 2:45 pace (to be fair I had no watch or km markers) turned into cramp at 30k and a 3:13 finish. Lesson: don't run like a numpty. And if you're going to run like a numpty, swim quicker than 1:24.
