Hour of Power on the Road

Had a day off yesterday because my legs felt quite tired after Saturday's 3 hour ride. I only had an hour to spare so rather than sit on the turbo I got out on the roads for an Hour of Power around my local loop. I last did this on 2nd March when I set a new PB of 313W.

The long rides of last week's training camp have affected the way I perceive time when I ride now; previously an hour felt like a long session on the turbo, now an hour on the road feels quite short and time seems to fly by.

I'd planned to set 275W as a base between the 450W+ 'bursts of power' but I was soon up to my old tricks and letting my power sit around 300W at base. After 20 minutes I'd averaged 311W and then I went on to maintain this out to 40 minutes when I started to flag a little. With 10 minutes to go my power had dropped to 308W average to I upped my game and even put in a couple of extra bursts in the closing minutes to get my power back up to a respectable 311W average for the hour, just 2W off my last session. Powertaps have an accuracy of approx +/- 1.5% so 2W is really neither here nor there.

Looking at the data, my HR seems a lot more stable and less peaky. This may just be a normal variation between different sessions or it may be a result of the distance and time of the training camp, time will tell. Average HR was 160bpm (163 last time), and NP was the same at 317W. So I probably haven't gained any fitness as a result of the camp, but I haven't lost any either!

Red = HR, Black = power

Hour of Power and New PB!

Thursday (2 days ago) was a rest day after 2 days of hard intervals and I planned a road ride yesterday. Unfortunately I was delayed at work and had other commitments when I got home so I had another day off and several glasses of wine and some chocolate too. Not exactly the highly disciplined training I had planned in November when this experiment started.

This afternoon I grabbed an hour to myself and headed out for another Hour of Power on the sunny roads, planning to repeat the hard session I did last week when I averaged a respectable 296W.

Today I felt great straight from the start and rather than trying to maintain 275-285W between the high power bursts, I just rode on feeling with occasional glances at my power. After 24 minutes I had averaged 317W (a new record) and then went on to set a PB right out to 60 mins. Other than a slight 'wobble' at 48 mins I just felt fine, though I was on the limit at the end and pleased to stop.

At the end I had averaged 313W compared to my last 60 min PB of 308W on 1 Jan. Then I tried to even out and control my effort, whereas today the Hour of Power workout is specifically designed to disrupt your flow and I would expect that to reduce your average power. So, I guess I must have got fitter. Last year's 60 min PB was 296W and I was absolutely shattered at the end of that, so I'm quite pleased.

 Average HR was low at 163, cadence was tightly grouped around 80rpm (yes, I do pedal slowly). 1100kCals for the hour and a relative intensity of 0.999, so hard work!

2 Hours of Power

I've been suffering from some early starts this week so I haven't felt like doing too much on the turbo in the evenings. I got a lucky break on Wednesday and was home early enough to set up for an Hour of Power. I last did this on 13 Feb and did a shortened 54 minute version so I needed to do full hour this time. Last time I suffered around 38 minutes and I had to back off for a while to be able to recover then complete the session. I was well motivated and keen to get the whole session done...

Unfortunately, my body decided otherwise. The good news is that I was disciplined at achieving the 275W (90% FTP) baseline and 450W bursts and that I lasted longer before I failed than the last time I attempted the Hour of Power, the bad news was that it was the start of a complete failure and I was unable/unwilling to complete the hour even though I knew I really needed to. My HR wasn't excessively high, peaking at 171bpm so I'm not exactly sure why I seemed to be suffering quite so much. Obviously there are daily variations in performance, but this seems like a fairly fundamental failure to perform rather than just a weaker performance.

Today I decided that I'd try the Hour of Power on the open road rather than suffering in the heat and boredom of my kitchen. I had quite a hard day at work yesterday, including getting a bad dose of CS gas, and several glasses of wine last night, so I thought I might be lining myself up for a big failure.

After a short warm-up (it was too cold to be riding too slowly) I got on with business. Above is the 60 minutes ignoring the warm up and cool down. The good news is that I managed to complete it. I had a bit of a brain-dump after 6 bursts and I forgot to do the 7th on time, so I threw in an extra one as soon as I realised and accepted that I'd have less time to recover before the next one. Heart rate was similar to the turbo session, peaking around 171bpm but I just felt a lot better throughout the whole session and never felt like I was going to fail. For the bursts I was standing for 20 revolutions as a practice mini-sprint and there's a lot more variability on the baseline as a result of corners, traffic, junctions etc.

The excellent news is that I was consistently above the 275W baseline and my bursts were well above the 450W targets too. As a result I managed a 60 min average power of 296W (equal to my second best ever recorded power output) and at the end I was even able to surge to 312W for the last 6 minutes, though I was pretty knackered at the end. The 60 mins of hurt had a relative intensity of 0.949.

So, overall a very good day to get me over the bad turbo session earlier in the week. It's also clear that riding this on the road MUST be easier than on the turbo, possibly as it was cooler and possibly as it was possible to to the bursts out of the saddle rather than seated on the turbo. I'm sure the wine didn't help, but maybe, just maybe, that's the answer!

Hour of Power - nearly

Today I did a shortened version of the infamous 'Hour of Power' devised by Bill Black. It's based around 60 minutes at a solid 90% FTP (for me 275W) with 15 sec bursts to 150% FTP (450W) every 2 mins and 45 secs. In the hour you should complete 20 bursts and 20 tempo intervals between.

There are lots of variations of the ratio of power but I looked at 90/150 and thought it would be achievable although I only planned to do 54 minutes as part of a 60 min workout. I'm going to add another 3 mins until I get to the full 60 plus warm-up and cool-down.

It started off well enough until I got to the 12th burst (the big red A) when I suddenly felt pretty crappy and was happy to back off and recover for 45 seconds or so. This also ties in with my highest HR and not being able to achieve the 450W burst. Luckily my HR strap was working today so it's easy to see that my HR was nowhere near it's 175 LTHR and only up to a measly 167-170 for the 6 mins leading up to the A. I know from experience that I usually suffer if I stay in this HR zone for too long so I'm not surprised that I hated it today, though I'm always cautious to not look at HR during the workout because I don't want it to make me think about stopping when I get up to these levels.

After the A I seemed to settle down a bit and just had a bit of weakness immediately after the bursts and then I did the last burst as an all-out 30 secs at 400W. And then I was done and beaten by Bill.

Next time I won't do anything different except stick to the 275W intervals and add another interval to take it up to 19 bursts. The time after that will be 20 intervals.

Overall stats for the 54 minutes:

Work done - 945 kJ
Average power - 290W
Average HR 160
Relative Intensity .93
