You realize the dragonflys don't have a carbon plate right? and as mentioned earlier there's no PHYSIOLOGICAL benefit to the lights (ie no drafting effects). The lights are of a purely mental benefit. Cheptegei and Gidey still covered the distance in record time. Shoot, Chep had to run the last 5k alone. The first pacer was falling off pace after 3k! Sorry but I don't think the lights help THAT much. I for one am enjoying the breakthrough.
I would argue there's a physiological benefit because it enables runners to lock on pace. It's no coincidence that all 3 WRs recently set were all run at a consistently even pace, almost as if they're running on a treadmill. So while it may not be as tangible as, say, track surfaces or shoes, it's still a huge physiological benefit.
100% agree. I said this previously, in both the 5 and 10 records, the evenness of his splits is ridiculous. He would be the first athlete in history to ever be able to reel off multiple (10+) laps within 0.5 of each other and this is HUGE when it comes to maximizing energy loss and efficiency. Go and look at the breakdown of the km stats between him and Bekele - do we really think Bekele was that bad at judging his pace compared to this guy? That is all wavelight.
