Well ii is a long jump. I will say that compare to hes best 100 m så are he getting a lot of help by the legs he is using. That ok but in competition with others not handicapped it Would be a little unfair. Normally you shall run at least 11 second to jump over 8 m and as i remember he i just running 11,8 for a 100 m. But it is good to se that the helping instrument can do so much to competition. And i hope that there will be more development in that area.
