rupp has been running fanastic at 1500/mile and 3000 this indoor season sharpening his kick to go with his endurance and he is confident with his olympic silver medal, geoffrey kipsang is a ferocious front runner who when he won the world junior xc over the favored isaih koech among others he led the entire race and held on, he just won the RAK half marathon in a very fast time, a couple of weeks before that he ran away and won by a huge margin in a 12k xc race against many top kenyans. in theory it is easier to stay behind and kick past the front runner, but kipsang is something else.
who would you pick? i think it could go either way hopefully we will see this at the moscow world champs and/or brussells.
