After briefly relinquishing the lead Monday, Nicolas Petit is back in front on the way to Nikolai. But, the pack isn't far behind.
Dallas Seavey, Wade Marrs, Mitch Seavey and Hugh Neff are within 10 miles of Petit.
The Nikolai checkpoint is 263 miles into the race.
So far, two mushers - Jan Steves of Willow and Martin Koenig of Montana - have scratched. Both scratched at the Skwentna checkpoint.
