Been training on a specific IM plan since the end of October, everything's looking promising so far although I'm still a tad worried about making the 1st lap cutoff. My swimming has improved loads, I did a 2.5km on Saturday in exactly 1 hour which is light years from where I was this time last year. I've taken my 1km time from 25:04 to 23:20 and last month swam under 2 mins for 100m for the very first time! Yes, I know it's still not earth-shattering but looks a lot different from my previous IM best of 1hr 52. Cycled 120km in 5 hours yesterday followed by a 6km run - endurance is not in doubt, it's speed!
