“…Moreover, based on the dietary subgroups, the samples share a similar age of approximately 39 years and have been competing in various distance races (10 km, HM, M, UM) with similar increases in age for each successive and accentuating distance. Previous research has shown the importance of age in running performance with the relationship of running economy [ 68 ]. Likewise, preferred race distance (whether HM, M/UM, or 10 km) is a key factor that has been shown to significantly influence training behavior [ 69 ], which therefore significantly affects best race time performance and vice versa [ 41 ].…”

The potential running or endurance performance difference based on following different general types of diets, such as omnivorous, vegetarian, or vegan, remains questionable. Several underlying modifiable factors of long-distance running performance, especially runner training behaviors and experience, diminish the clarity of results when analyzing dietary subgroups. Based on the cross-sectional design (survey), the NURMI Study Step 2 aimed to investigate a plethora of training behaviors among recreational long-distance running athletes and the relationship of general diet types with best time race performance. The statistical analysis was based on Chi-squared and Wilcoxon tests. The final sample (n = 245) included fit recreational long-distance runners following an omnivorous diet (n = 109), a vegetarian diet (n = 45), or a vegan diet (n = 91). Significant differences were found between the dietary subgroups in body mass index (p = 0.001), sex (p = 0.004), marital status (p = 0.029), and running-related motivations for well-being (p < 0.05) but not in age (p = 0.054). No significant difference was found for best time half-marathon, marathon, and/or ultra-marathon race performance based on diet type (p > 0.05). Whether the vegan diet is associated with enhanced endurance performance remains unclear. Although, the present results are suggestive that 100% plant-based (vegan) nutrition is compatible with distance running performance at the least.

Introduction: Carbohydrate (CHO) availability sustains high metabolic demands during prolonged exercise. The adequacy of current CHO intake recommendations, 30-90 g•hr-1 dependent on CHO mixture and tolerability, to support elite marathon performance is unclear. Purpose: We sought to scrutinize the current upper limit recommendation for exogenous CHO intake to support modeled sub-2-hour marathon (S2M) attempts across elite male and female runners. Methods: Male and female runners (n = 120 each) were modeled from published literature with reference characteristics necessary to complete a S2M (e.g., body mass and running economy). Completion of a S2M was considered across a range of respiratory exchange rates, with maximal starting skeletal muscle and liver glycogen content predicted for elite male and female runners. Results: Modeled exogenous CHO bioavailability needed for male and female runners were 93 ± 26 and 108 ± 22 g•h-1, respectively (p < 0.0001, d = 0.61). Without exogenous CHO, males were modeled to deplete glycogen in 84 ± 7 minutes, females in 71 ± 5 minutes (p < 0.0001, d = 2.21) despite higher estimated CHO oxidation rates in males (5.1 ± 0.5 g•h-1) than females (4.4 ± 0.5 g•h-1; p < 0.0001, d = 1.47). Conclusion: Exogenous CHO intakes < 90 g•h-1 are insufficient for 65% of modeled runners attempting a S2M. Current recommendations to support marathon performance appear inadequate for elite marathon runners but may be more suitable for male runners in pursuit of a S2M (56 of 120) than female runners (28 of 120).
