My times were 3:19, 3:09, 2:57, 2:44 and Liam was just ahead of me so I don't think he was slowing. You seem to have been pretty consistent really.
The 4:38 was definitely slower just because I was less confident of where I was landing my feet and I could only see that becoming worse. Times went back to about the same pace I had been doing when we did the last two on the firm, even surface even though most of that was dark too.
I definitely slowed down but more due to wearing myself out on the first two since I took it out way too hard. Sten was very consistent, just four seconds between his fastest and slowest across the six circuits. I had 21 seconds between fastest and slowest although managed my 6th faster than the 5th and that felt okay.
