IRONMAN 70.3® Oceanside

Jeanni averaged ~56g of carbohydrates per hour, her lowest fuel intake of the season, mostly using PF Carb & Electrolyte Drink Mix, PF 30 Gels, and PF 30 Chews. Unfortunately, she struggled with GI issues during the race, possibly from the stomach bug she’d picked up the day prior, which prevented her from finishing her drinks and limited her intake of gels. Therefore, her intake fell significantly below the recommended range of 90g/h for optimal performance in a race of this length and intensity. Jeanni did manage to front-load her intake, achieving over 60g/h on the bike; however, her consumption dropped to just ~23g/h on the run. This tapering in carbohydrate consumption is not uncommon and can be an effective fueling strategy in triathlons, but Jeanni took this too far with such a low run intake. We hope to see her aim for the higher end of the recommended range on the bike, with a more balanced approach to her run intake when she is in better health.

Given the mild conditions, Jeanni’s fluid intake seems adequate, but with a closer look, it’s actually on the lower side for her individual losses, especially compared to her intake during previous races like The Collins Cup, and the 70.3® World Championships this year. Her fluid consumption at this race was certainly hindered by her stomach comfort and although she peed once at the start of the run, indicating she was not *severely* dehydrated, she rated her hydration at a 6 out of 10, noting she could have consumed more, especially water, during the run. Jeanni took on a relative sodium concentration which effectively replaced a significant portion of her sweat sodium losses, given her high sweat sodium concentration, and did not experience cramps. Since she felt the extra PH 1000 on the bike was unnecessary in the overcast conditions, she may have been craving a bit more fluid to replenish her losses more in line with the amount she typically drinks.
