I did a Kosmin test today which predicts a 2:05. But 4 weeks ago I did a 2:17, altho it was very poorly paced race by me, 63s for first lap and there was strong wind. I was last all the way (I'm not an 800m runner and was a guest in the race) and metres behind the pack so it was hard to remain 'interested' in maintaining a good pace. I think without the wind and better pacing I would have done about 2:13. That said, what should I do this Saturdays race, in terms of pacing the first lap. And should I probably go for 2:08 rather than the Kosmin predicted 2:05?
