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)

    World Records Men's Swimming: 1500M LCM 14:34 / 14:10 SCM WOmen's Swimming: 1500M LCM 15:42 / 15:28 SCM Men's Track: 5000M 12:37 Women's Track: 14:11 Presumably you should be about 10% slower in the swim than the run. The Men's 5000M record is absurd. Good way of looking at it. Obviously it's harder to control conditions for a 5K road race (terrain, weather, etc.) than it is for a pool race, but comparing to a track 5000M is probably about as close as one can get. I guess I have some work to do. :)
