Naturally, I couldn't leave it alone so I promptly set off to confirm the accuracy at a trustworthy American track. I had some 1 minute fartleks scheduled so I changed the route to end at a track and had some of the intervals changed to 400's just to check. I hit 66, 66, 65, 63! I was wrong to doubt the Finnish track. It was bigoted of me to think that 400m is somehow less in Finland and for that I am deeply sorry... but I had to be sure.
I am so pumped with that speed. Cutting 6 seconds in a 400 over one season really is getting me geeked.
And with that, I am definitely in for the Ironman in December!
