Open 5K vs Sprint Tri 5K

I set my 5K PR inside of a triathlon today. I was wondering what a good estimate would be for an open 5K? Something like -5% or -10% off of a tri 5K? I know I could just go run one but… I wanted to wait a couple weeks before putting in another hard effort.

Thanks

You should be able to go 30-45s faster in an open 5K.

did an open 5k last weekend (hard & windy course) and a sprint tri today (easy / flat course).

open 5k was 43 seconds faster. So course dependent…i’d x2 the 30-45 seconds estimate.

Encinitas Sprint? That’s where I was.
