Once you release personal records I thought in short time you would include it for swiming. Like 1000m/1500m/3000m/5000m for Open Water Swiming and also for Lap Swiming like your personal best from any interval in any activity for 50m/100m/200m/400m/500m/800m/1000m/1500m/2000m. Hope you can include that in the next update.
