"Mathy" pace calculation question
I'm using this year to begin my OWS as the goal transition.....
away from triathlons (my body said, "ENOUGH" with the running).
Anyway....this year's goal is to swim in as many different conditions as possible, and start to work out feeding/nutrition and all that.
I've done one formal event, current assisted, and had a blast.
The rest of my swims have been in the lake -- launching from a friend's house.
When looking at all of my training swims, I am generally holding a 34-35 minute mile (including time spent feeding). The lake is dam controlled, so there is sometimes current if we're in the river channel.... or wind.
For my current assisted swim, though, I held a 26-ish minute mile. The said that there was 13k cps being released from the dam that day. From what I can gather, that's about a half-mile per hour flow rate.
1) Is that approximate flow rate correct?
2) How do I calibrate my pace while also taking in to account the flow rate? Is the flow rate subtractive in some way? In other words, is there a way to estimate what my pace might have been over the same distance if there'd been no flow -- having only the information of flow rate and actual pace?
Unfortunately (or maybe fortunately), I'd forgotten my watch at home that day, so don't even have stroke rate data to examine for the down-stream event. But, it was a glorious "naked" swim..... I only almost ran into one channel marker buoy. (Dark green channel markers are really hard to see from water level!)
