vStaR covers pretty much all of it.
Please do not take it the wrong way and this is saying it with a different form of respect for those on Tri coming into Ultras (more spec TNF100)
Having being on both side of the fence (as a runner and as a TNF100 'front-of desk'), there are a lot of Triathletes who went into TNF100 with lots of confidence of doing well (Many with good Ironman times, including a few of sub 10hours!) This is esp evident when at rego, you see people showing up with Hawai Ironman / port macquarie..etc...)
Unfortunately, thats the exact same group of people who struggled to get from CP4 to CP5 ; Or are completely spent @ QVH CP and wonder why their training let them down, sneaking in under 20 hours....
I for one cannot swim 350m, let alone 3.5km. And to cycle 180km and then run a marathon, while I think doable, requires a disipline person. I am happy to just run, run and run. And thats where TNF100 is a different event all together. Rico is right, Triathletes have a good record with 6FT, with one of them in the top 10 position 2010! 6FT being a sprint Ultra has the same "sprint" elements of Tri.
TNF involves the carrying of the pack, the runs, the walking (of flats), the walking(of hills), the walking (of stairs), the passing (of farts and runners...) You fight to get a space at the start of the swim, here be prepare to fight to get to the bottle neck (20m after start of 6FT ; jamison valley towards Golden stairs for TNF100)
On that note, if johnyboyrun is able to apply the same discipline and work specific exercise, I say a first time sub 14 is way within your ability...
p/s: 5Kg is excessive. You wouldn't cycle with weights on your bike would you? At least I wouldn't
