1:38:42 for me but I had a mare!
Thursday's ride was cut short on the hill as the belt on the Kickr snapped. Put another on today and did the re-run (earlier than others) to set a time. Was going OK until I got the 8-10% sections on the hill when the belt started slipping

Don't get wheel slip on the Pro so mega frustrating to get it on the Kickr. I was about 1 min 20 secs behind Del at that point and closing in ... anyway, got off the bike and tightened up the belt further and this seemed to help. I'm now 6 mins down on Del so not great
I then hit a 4.7% section (which had followed a -3%) section, and the resistance on the trainer stayed like I was on a downhill. Problem is, I was spinning out so couldn't push much watts. As such Bkool was seeing my 90 watts, on a 4.7% incline and setting my speed as something silly like 5 kph ... needless to say everyone else on the ride just zoomed past me - probably lost another minute on that section. Then, on the final -13% the resistance stayed high so I'm having to grind my way 'up' a -13% down ... FFS, more time lost.
After these frustrations I was shot on the downhill sections and nothing left in the legs. Ave watts by now had dropped below 220 (watts were over 240 when I started to get the belt slippage).
A frustrating ride, all in all
