Runners using Vaplorflys in track races

Some pro's use a custom VF 4% with spikes in the bottom (i.e gwen). I wouldn't use them indoors because of traction on the turns, but if the track is dry and your track race is long enough that traction isnt an issue then they are more efficient and will shave time (see the GVSU study in old thread). There are pro's wearing them for long track races, and there were a bunch of top collegiate guys wearing them for 5k/10k at nats.

i tried wearing them in a trail run this past week. went out to warm up at race pace in them.....nope

Laura Muir was using a custom spike with enlarged midsole volume indoors.

10k on track it makes sense. 5 too.

Physiologically it will help with 1500/3k, as long as you like the feeling.

They don't work well on trails. The plate seems tuned to rebound off concrete or hard surfaces.

Why does the race have to be longer? It should be governed by the pace.
