He broke the world records in 3000, SC, 5000, and 10000....in less than 3 months (81 days).
it is a huge pity henry didn't run a rested 1500 with pacers in '78 ( albeit he ran coupla low key mile races early on & 2 at end of season when running on fumes )
his 3k wr of 7'32.1 was incredible
i believe he split 3'50/3'42 with a 57.4 finish !!!
so, basically a jog to 1500m ( i don't know if he got much/any pacing ) then a huge push
it's pretty obvious he couda gone 7'30 that day at even pace
i'm also pretty sure he wouda been in 3'33 shape that day ( he was not that disimilar from jipcho who went 3'33.1/13'14+ ( latter fractionally outside 13'13wr - ben's clocking though was in a proper race, not a tt ! ) ) as you'd expect most 7'30 guys nowdays to be capable of 3'32/3'33/3'34
the 1500wr in '78 was bayi's 3'32.1
i don't think henry wouda quite broken it, but possibly couda run it close if he'd rested a bit & did a bit pf speedwork mid-season
no one has held every wr from 1500 - 10k certainly not simultaneously ( i have to check nurmi though ), but henry couda come damn close !!!
