47th out of 175 in 29 degree heat !!
Didn't feel like I was riding well / fast at all.
Probably linked to beers n curry the night before (having to go back to sleep once I'd got up!) then nearly keeling over with heatstroke on the second half.
I lost about 10 places at the end, in a situation where I normally make places up.
I think without the heat effects I'd have ended top 30. Never mind - bring on round 5 next week !
