Pausanias Description of Greece 3.12.2

[2] It is said that Icarius proposed a foot-race for the wooers of Penelope; that Odysseus won is plain, but they say that the competitors were let go (aphethenai) for the race along the Aphetaid Road. In my opinion, Icarius was imitating Danaos when he held the running-race. For Danaos contrived the following plan to solve the difficulty about his daughters. Nobody would take a wife from among them because of their pollution so Danaos sent round a notice that he would give away his daughters without bride-gifts, and that each suitor could choose the one whose beauty pleased him most. A few men came, among whom he held a foot-race the first comer was allowed to choose before all the others, after him the second, and so on to the last. The daughters that were left had to wait until other suitors arrived and competed in another foot-race.
