The original article [1] contained some minor errors in the reporting of sodium intake of three participants during the race.

The final paragraph of the Discussion section in the original article has been updated to correct the initial reporting of sodium intake from 49 g to 20.9 g; associated errors in Fig. 2 and Table 3 have also been corrected.
