When the green knight picks up his head and says come find me in 366 days at the green chapel. “Gawain, whose thoughts, as ours must now do, ran on ahead of him to New Year’s Day a year hence”
hope he can keep up
At this point in the story Sir Gawain must start his journey to the Green Chapel "Bravely but sadly, Gawain rose to his feet, 'Uncle, good King, my dear friends,' he said 'the time as come for me to say goodbye.'"
Is he okay
This point in the story Gawain is getting ready for his journey and meets his horse "at once to the courtyard to Gringolet, his waiting warhorse, who was as magnificently dressed and armored as his master."
As he crosses the threshold he finds help "High above and ahead of him flew a flock of geese, pointing the way north, a singing arrowhead in the sky."
He faces many challenges his hardest is the cold. "It was the cold. Sleeping or walking, the sleeting wind cut through the armor and chilled him to the very bone."
