Well I thought a while back that faster pace was better for my form, but with a few races under my belt bare, and then back in shoes for the last one, I don't think that is the case for me anyhow. But there could be a balance, a fast pace might help with form a little, but pushing it beyond that into race-pace starts to degrade, especially at a faster 5k race where my feet feel like there moving so fast I don't even know what’s going on down there. But my feet have come away from most races better off than some of my training runs!
Cadence isnt my issue, well it is - but because so I still listen to a metronome app. I usually play the metronome in the background along with music, and I know it sounds weird to listen to both but I've been doing that over a year now.
Form is a funny thing. When I am bare now, I don't even think about it for the most part. But in shoes, when I have to concentrate, I have a hard time remembering all those little things about form from when I was new to bfr. And even when I try to implement them, the lack of feedback leaves me unsure if I am even doing it right. I end up trying to shift my feet all around landing differently, and never do find anything that feels right. Frustrating.
