How Can I Improve My 1/2 Ironman Run?
I have been building up my endurance for triathlon slowly over the last few years.
I am pretty happy with my swim and bike splits but when it comes to the run I lose all my time that I made up in the bike ride. I get off the bike and my legs feel too weak to run so I end up running slower during a triathlon than I do during my training.
In my last triathlon race I had a fast swim followed by a 2:30hr bike ride but my run was 1:54 which cost me the race.
I just don't know what to do to get fast in the run. I have never been a runner. I am short and have short legs. When I make three steps others make one.
I just don't know how to get speed going? I do a lot of uphill and interval training but maybe I should work more on long distance?
Can you help me?

It is likely that the problem is not actually your speed, but your fitness. The fitter you are the better you will be able to follow up the bike with a good triathlon run. As you get fitter you will get faster, but your training needs to be orientated around triathlon.
Things to consider including in your triathlon training:
Short fast runs off a decent hard bike (2 x 5-min running at just over anticipated race pace) - get used to the feeling of changing disciplines and running out harder than expected.
Tempo runs off long steady bikes:
So you are not too fatigued from the bike, but you have been in the saddle long enough to create some fatigue and activated all your cycling muscles. Then as you run tempo (10-15% slower than race pace) you are having to overcome this postural change and activate the muscles under load in a suitable way.
If you run with a high cadence try to ensure you are doing this off the bike. It needs to be a longish run judging by the durations you are competing over.
Other things to consider:
Are you taking on enough energy to provide the fuel for this duration? Have a look at our answer to another question about race nutrition for some advice on when and how to fuel during a triathlon race.
Pacing on the bike:
Front load your effort during a race, and then back off more over the last 10-12K of the race. This will require discipline as people you have passed may come back by. But you will then be in a better position to run off the bike. Practice this in training.
Fartlek training for speed:
This is continuous running but including variations in pace. This will help to develop cardiovascular fitness as well as conditioning you to run over the longer durations. Use hills on your long steady runs but steer clear of them in short interval reps. The distance you are racing over (half-Ironman) are not orientated around speed and power, but endurance and cardiovascular fitness (the engine).
