To mccaffrey dude......re times Doha.......there are a lot of variables ....one of those being the health of an athlete and his / her mindset going into major champs ....health good Possible management of injuries etc .....and been performing consistently ...then this bodes well .........others factors include the venue ....so Doha is ideal for the shorter stuff ..,,,times are dependent on competition ( usually ) ....i.e 8 world class 400 meter hurdles in a final after quality heats ....then ....one can talk about possible fast times .......and this includes lanes ...eg the 200 meters ...gentler bends etc .....a good indicator is what a coach is seeing in the run up to an event ....and how the athletes training is being managed including confidence .....only the athlete and their coach know really where they are at pre champs ......and heats are usually ( and I say usually ) a decent indicator of where an athlete is at ...and how comfortably they deal with opposition ...doing enough to enable good lane draw ,.,.,another factor include time between events especially if athletes are planning to double up ..eg possibly warholm ..,,maximum rest for maximum performance .....ie a consistent no frills build up including competition leading up to events ....I have suspicion tortu will make a final pending on semi final heats ......because his start were not great ...so he needed time ...and he is a real competitor ..so I feel quietly confident for him ....obviously guliyev is a major medal probability ....and I have a suspicion guliyev will push menneas mark when competing against lyles in a final ........and schippers will medal over 200 ...I reckon she and her coach have been slowly building towards Doha ...and she is a fierce competitor .....also Gemili will make a final over 200 .....and as always there will one good surprise or two ......Greek long jumper ,,,possibly .....and the 100 meter relays should be interesting .....as should the 400 meter relays ......
