I have a 10K "Twilight" Run to do in 2 weeks time twilightrun.com.au/. I know that I can run 10K - have done it quite a few times - but the question is -- can I run it at 7 mins per K pace and even more importantly at a temp of 29.5C and 60% humidity. It starts at 5PM and I always run in the early morning so I tried it today at 5PM - I managed to do 6.6K ( all that I had planned to do at 6:53 per K) but I was quite tired by then ( but the temp had dropped a half of a degree by then ) . The next 3.6K is going to be interesting!!!! I have 5 more training runs left after today . I am going to take it out to an hour in practice and "hope" that the excitement of the day gets me the rest of the way across the line.
