Suggests (in rats) 39% of endurance performance is inherited.
http://ajpregu.physiology.org/content/275/5/R1455.shortBy the way there are plenty of candidate genes linked to endurance performance in humans. I don't know if you have access but check out:
http://www.springerlink.com/content/kdrvbp3xlv1tct22/fulltext.htmlTreadmill running was evaluated as a phenotype for selective breeding for high- and low-endurance performance from a starting population of 18 male and 24 female outbred Sprague-Dawley rats. Each rat was exercised to exhaustion once per day for 5 consecutive days. The treadmill was set at a constant 15° slope, and the initial velocity of 10 m/min was increased by 1 m/min every 2 min. The total distance run on the single best day out of the five trials was taken as the measure of endurance performance. The original population (males and females combined,n = 42) ran on average for 396 m. The two lowest-performing pairs and two highest-performing pairs were selectively bred through three successive generations. After three generations of selection, performance of the offspring from the high selected line averaged 659 ± 36 m (n = 20), whereas low-performance offspring (n = 13) averaged 388 ± 28 m. The narrow-sense heritability, calculated as the regression of individual offspring performance on midparental value for each family, was 0.39 across the three generations. This implies that 39% of the variation in running endurance performance between the low and high selected lines was determined by heritable factors.

What is wrong with you guys? Seriously.
We are talking about that ONE study. Not the entire field of genetics. I know how genetics work.
