Do you think most people (or even 50%) in UK cycling clubs could do this, 60 min 40k without aerobars ? I know you din't say that was the case, I'm curious as to what you think.
I would *suspect* that a good half of the senior racing members of any Road club would be disappointed to not be within striking distance or under the hour for a 25 mile tt. Especially with that much training time available. And on a flat course.
FWIW I hate time trialling with a passion, and have even answered my mobile whilst racing (anything to break the boredom) and haven't actually gone slower than an hour over 25 miles (as a racer) and even when 20 kilos overweight and massively unfit can still get within 3 minutes of the hour. (All on a Road bike)
I'd disagree, 60min is the benchmark, but its for TT rigs not road bikes. Whereas some clubs definitely would do better than others, i think nationally a relatively small percentage will be able to do this. I'd say its the benchmark point at which people consider themselves "decent" or "good" cyclists. But realistically I'd expect any UK 2nd cat or above to be able to do a 60 min 25 on road racing equipment. We do need more roadies TTs back again.
Time trialling is all about connection with your body and being present with the pain.
I've been down to 22min 10milers and 56 25s on 8 hours a week training on road bike. But every minute must be quality training at that level. No room for junk miles!
As previously stated 20min threshold intervals are very good, but so are long sweet spot sessions (80-85% ftp) for upto 1hour at a time. Shorter above threshold intervals like 3 or 5mins are great but not as beneficial for an hour of pain.
This is alledgedly a generic template of what matt botrill (2nd to alex dowsett in the national TT) does for his training, looks like a good base
Monday - 2hrs Level 2
Tuesday - 15 mins L2, 1hr sweetspot, 15 mins recovery
Wednesday - Rest
Thursday - 20 mins warm up, 4 x 4 minute level 5 intervals
Friday - 15 mins L2, 1hr sweetspot, 15 mins recovery
Saturday - Race
Sunday - 90mins Level 1-2 recovery ride.
