I like the idea of weight categories, probably less competition in the 75kg and more category for endurance running than the under 75kg runners.
In this race there was slightly less competition in the 75 kg category. vs. lower weight categories. Much less competition in the 95+ kg. weight category!
Hmm...even at my bulkiest I would need to gain 25 pounds to get into that category. 75-84kg would do it for me though.
