Bit uncomfortable to begin with shorts top etc, wasted time pulling at those....pretty hard going.....knew would beat quickest.....just wasnt as smooth as normal, when got to 10k out seemed to get it together a bit and new strategy of counting down 9k to 7k and 7k to 5k......at 5k got a lot easier and alternate sprint/normal 100m's 1 k out....very sweaty maybe room a bit hot today
