I Don't Get It..

[guitarboogie]

Clue reads "List Ron compiled for an opening in the boat race"
Solution is "nostril"
Can get that nostril is anagram of list ron and that it's an opening insofar as it's an orifice but..where does the reference to the boat race come in ?...I don't get it ? Clarification would be appreciated.
Regards, Tony Butler
