Did my first 1500m straight-through swim in forever today (according to my records I last did this in September 2008? No time from then, sadly, or perhaps fortunately). Today I got a time of 28:12, with a pace of 1’52" for 100m: looks like splits ranged from 1’43" (for the first 100m), pretty consistently around 1’57" in the second half, and 1’51" for the final. Um … I’m not sure how the Apple Watch is calculating that; those numbers don’t seem to make sense.
I have no idea how to pace myself for that. I was definitely too fast for the first 100m, but I should be able to maintain a slightly faster pace through most of it. I need to try that more often; most of the time I’m swimming 100m sets, so I’m pretty good at pacing those, but I’m too unfamiliar with other distances.
That pace is a fair bit slower than what I was doing almost two years ago, but it looks like that time I was pushing myself, and I finished today feeling like I hadn’t pushed myself enough.
