Thinking about the 1000K and 1200K distances ...
For those events, I usually try to cover over 400 km ... closer to 475 km ... on the first 'day'. Then I know I just have to make it a relatively short distance until the 15 km/h time drops and I can kind of relax.
According to the Audax Australia website:
For 1,000 km BRM rides, intermediate control closing times are based on 15 km/hr up to 600 km and 11.4 km/hr between 600 km and 1000 km.
Also, the start times for the 1000K and 1200Ks have been different. The ones I've done have tended to start late in the evening or very early in the morning whereas the 600Ks have tended to start about 7 am. I am not a morning person and perhaps that gets me off to a bad start right away. I have wondered about starting a 600K at a different time.
And maybe when I'm riding a 600K, I need to pretend I'm riding a 1000K.
