1500m (1650yd) swim vs 5km (3mi) run

yesterday I swam a 1500 to get a sign up time. it's been nearly 6 months since i have swam anything over 400m. I had no idea how I should swim it, or how it would feel during. took off way too fast 1:15, then 2:25 at the 200 and 5:20 at the 400. but then averaged about 1:25-1:26 for the rest and ended upw ith 21:10. it got me thinking about a 5km run. I don't run, but it seems that almost every spring I decide it's time to start and i do run 3-5 times and I always use a 5km as a test/goal distance. my goal for the 1500 in 3 weeks is to be under 20:00 so I have 3 weeks to learn how to hold a 1:20 pace, as well as to prepare mentally how it feels to swim that long. but I find it funny that my goal for the 5km has also been to run it under 20:00 anyone else have similar times for the 1500 and 5km? (1650yd vs 3 miles)

  • Please accept my appology, I incorrectly applied the formula 5k's @ 20 min = 1.5 km ~ 24:00 LCM I think you were right the first time. 1.5 km swim should be roughly equal to a 4 x 1.5 run, or 6k. Since he is only running a 5k, the time should be 5/6ths of his 1.5 k swim. The only mistake I can see is that you spelled Thornton wrong. You left out the first n.
