Hillingdon Duathlon 9 November

Are there any dualathons which are bike and swim only?
I hate running but am pretty good at the other two and really want to do something like this
For triathlons, do you reckon its possible to just blag the running leg if your swimming and cycling is strong. Or is training really needed?

MikeC, you can blag the run on a Supersprint (run is 2.5km) and still do well and maybe blag it at the most on a sprint (run is 5km) but at olympic distance, you will need to but in some training, tough enough to run a quick 10km, but after 25 miles it always hurts :(
