Correction to: Sports Med 10.1007/s40279-017-0811-2

An Online First version of this article was made available online at https://link.springer.com/article/10.1007/s40279-017-0811-2 on 16 November 2017. An error was subsequently identified in the article, and the following correction should be noted:

In Table 1 of the original publication, an error was made in unit conversion. Values in the row entitled ‘ECOT’ should have been further multiplied by 60 min/h and divided by 1000 m/km. A correct version of Table 1 is provided below:

Table 1.
