Being shortish is an advantage in distance running for the following reasons.
1. Better power to weight ratio
2. Shorter people weigh less, and it is more economical to carry less weight.
3. It is more efficient to move shorter levers (legs and arms) than longer levers over long distances - again we are talking from an 'economy' point of view.
4. Shorter runners are usually biomechanically more efficient, and this contributes to better form and less injuries.
5. On hills (up and downhill) shorter runners have a clear advantage over tall/lanky runners - they are able to move up and down more efficiently and economically.
For these reasons and others, shorter runners are usually at the front.
Possible ideal height and weight for distance runner.
1.70 cm/ 50 kilos (male)
Most elite runners are around the '19' number on the BMI tables. Check you BMI, and see how you fare.
If 1 was true, then the 100m would be dominated by small guys. Mo Greene is the smallest global champion in recent years and even he is just about on the average. Bailey, Christie, Lewis, Borzov, Hayes etc., all well above average. So if power-to-weight ratio is related to height it must be the opposite to what you hypothesised.
2 True, in that weight is related to height, but taller people have larger lungs. There are plenty of examples of tall and short athletes in the endurance events.
3 Shorter legs have to be moved at a faster cadence to make up for a shorter stride, and so tire more quickly at high speeds. Hence the predominance of tall athletes at the 200-1500 range.
4 Is this conjecture or has there been a study done to show this? It's an interesting possibility.
5 Since taller runners can take longer strides, it follows that they can run downhill quicker. As regards uphill running, power-to-weight ratio comes into play so see 1.
Haven't seen much evidence for your conclusion. For every Kenenisa Bekele and Haile Gebrselassie there's a Paul Tergat or a Craig Mottram.
On the distaff side, look at Paula Radcliffe or Sonia O'Sullivan (Sonyar Ro Sullivan for you Brits).
