What's A Good Relative Run Time Off The Bike?

Sure there are so many factors at play and there's the whole "how you feel on the day" thing, or it could be windy and the bike messes you up big time. But putting all that aside what, if any, theories do you use to work out a time you'd be happy with for the 10k run off the bike.
I know what my best 10k time is and I know what I can fairly comfortably do in a 10k training run (about 15sec/km slower than fastest 10k). I have told myself that I would be happy 30sec/km slower than my best 10k time.
Just wondering if anyone else bothers with this or if I am on my own over analysing (again)...

I don't bother trying to work out a goal run time in a tri. Apart from the factors you mentioned, the biggest problem is that triathlon run courses are notoriously innaccurate. I have run "PBs" in a triathlon and I know I don't run faster off the bike.
Better measures are how you feel on the day, compared to normal - do you feel strong, can you put in a good surge over the last k or so, etc. Also look closely at the results for your category place for each leg and see how they compare. If you are a good runner then you would expect to place higher in that leg than the bike and swim, and make up time on the more experienced triathletes over the run leg.
If you race the same course again in the future, then you can start to compare times. Good luck!

When I started triathlon I came from more of a riding background and my run off the bike was 5min slower than fresh. Over time both legs improved and by run differential at last race was 1min16sec. These times are all from the same run course so this can eliminate the "notoriously inaccurate" factor.
Better, fitter athletes see less variant between the 2.

I generally find I do about a 2-3 minute differential over 10km on a good day - but it's easy to blow out to a 5-10 minute difference on a bad one

All things being equal you normally can add about 10% to your 10k run time so if you are a 40 min 10k runner, you will look at around 42:30 give or take depending on the course.
A good tip when straight off the bike which is where most people struggle to find their legs is to take smaller steps and keep the tempo quick. Keep a nice fast turnover till your legs come good which is generally for less experienced people about 8 - 10 minutes in. Once you feel legs coming good you can start to settle into your normal stride.

I purposely didn't post a time because I didn't want it to turn into one of those posts I've seen in the 10k forum and I thought a relative time was probably more appropriate ie it's going to be slower but how much
Anyway, with the "it depends on the day" thing set aside it sounds like my 30 sec/km (ie 5 minutes slower over 10k) might be a good goal unless everything really falls apart.
I also seem to be rushing a little off the bike. I am having trouble pacing myself off the bike and I end up going too fast because it just simply doesn't feel normal. This has happened in every brick session that I have done. So on race day I don't want to get caught out by going too fast early and then dying 5k from home. I'd rather set myself a more realistic pace early and then hopefully have something left to put in a bit extra on the way home. I guess we'll see what happens, not long to go now.
Thanks again.

sounds like you have never raced - doing a OD is a pretty good start though!!!!
I think it is one of those things you will find as you go but being the first take it easy right off the bike within reason, I like to build up so take it easy then decide in the 1st K what my pace will be then take it from there - too many factors are in place on race day with the 3 disciplines (hard swims, windy bike leg etc)
your ideas might work for you so give it a go - some plannning always helps...

So I have done it now, and I had the bad one! Everything was hurting, especially running uphill (hip flexors I think, I guess from the bike). Anyway, I came in over 51 minutes and was hoping for 47:30 based on a 10k race time around 42:30. Anyway, I am sure there are lessons to be learned, but first there are things to be fixed, off to the physio...

Trust there is no serious damage done and you'll be back to racing soon.

I find myself going out steady then trying to speed up near the end and use fast twitch muscles near the end of the race.
Just wondering what the psychology of the opposite approach is - ie going out fast in the run off the bike? i know some people who swear by it (and are very good..ala Ms Snowsill).
cheers

There are a few studies that have shown the biggest area for improvement amongst high level competitors is over the first 1-2km of a 5km run in a sprint distance race.
Personally I managed a couple of seasons where my run off the bike was faster than my fresh run times for 5-10km. The majority of my training were combined sessions in various formats, and order plus only one long session per week per discipline. The key session I tend to credit the most with improvement was run-bike-run repeats performed in a group. The first couple of repeats were used as warm-ups and focused on the skills of transition then the rest 2-8 were raced. Distances were something in the range of Run 100-200m/Bike 2-4km criterium style circuit/Run 200-500m.

I like the idea of trying the repeats, I think I'll give that a crack next time.

So try incorporating a short run after your long bike. Just 10-15 minutes or so. Run it as smoothly and as hard as you can, without belting it at your 5km race pace. Get the legs used to running 'well' off the bike, so you have little transition-lag
Incidentally, I did my first off-road tri on the weekend - and do you think I actually practiced a mtb brick in the lead-up?? I certainly didn't - and good lord did I suffer because of it! Let me tell you here and now that a 'run-off' the Tri bike is world's apart to a 'run-off' the duallie

downside is puffing like steam train for that first 2k before settling down to business. my first km has been teh fast on a few occasions for this reason.
same as miners, 1.5-2mins is about right but has been as high as 7-10mins on a bad day (when i went too hard on the bike). best difference for me was 42:58 (straight 10k) vs 44:xx in OLY tri last M'ba. Noosa last year was 50:48.

Our saturday training we do some ride/run and swim/run bricks, as well as the odd tri. What I try to do is on my sunday rides I stick my runners outside and do a lap or two of my block which is about 1 mile around. Just to get used to the feeling.
My local tri club also runs a series of 6 short course tri's over spring/summer, and some duathlons during winter. I'll keep up doing them. And at 10bucks a race, it's good value.
