Looks like Troy is off to a flier.
If you look to the list of names on the right of the page... you can filter the list of names by miles ridden. (just click on the little arrow above the distance, once puts them from least to most, twice lists them from most to least)
You'll see that Troy currently looks like he's 6th or thereabouts.
but if you click the little + beside each riders name, you'll see their details. Including which distance they're racing in.
Most in front of him are doing the shorter 350mile event, and one is even doing the 150mile "sprint".
He's currently leading the
1,000mile by around 20 miles over the next rider. But he's only a 101 miles in... and it's a long way to Nome...
