Wardian, Olson and Herron have ZERO multi day experience.
Predicting that they would do well is like saying a good 1500 meter runner would crush the marathon.
This is expected letsrun style. Most here think that the top Marathon runners would crush all ultra running records. Anybody who has a little knowledge about ultra running knows that is not possible.
Wardian, Olson and Herron are fine runners but it would have to be seen what they can do in multi day races.
Wardian seems to be the most flexible of all of them. So I would give him the highest chance of succeeding in a 6 day race.
