Mantz is a very good runner but I think he would need to improve his under distance times to some extent to be more of a player on the big scene. For example, he would need to get his 1500 m down to about 339 or equivalent to run the 356 or 357 mile. This would then help him to become A 1315/ 2730 (5000/10,000) type runner. This would then point to 61 minute half marathon and around 208 for a marathon. Now, in the super shoe era, everything is possible.
