Hi knowledgeable people
I have started this VO2 block thingy and have done some lower PL VO2 workouts to just remind me how to work hard above threshold. But I have a few questions
These lower PL workouts tend toward shorter efforts. I did the first one inside on the trainer in erg mode and also soon realised that the ‘feel’ of the workout was very much spin fast - it felt like an effort up a slight incline/false flat.
However, for most of my day to day riding/big rides, the only time I am really likely to do VO2 efforts is up steeper hills - eg part of an XC race or when a threshold climb suddenly ramps up to 25%.
So I’ve done the last two workouts outside instead on climbs with varying gradients and varying terrain. Is this a good idea or should I just stick to the trainer?
It’s a lot easier for me to put the power through on a climb, and on these 1 to 2 minute efforts the Garmin tells me that I am just working anearobic/neuromuscular stuff. Is this a problem? Should I just sack off the shorter efforts with the longer recoveries (I don’t mean 30/30s I believe those work by shorter recovery so you don’t shift the lactate in time for the next effort?) and focus on longer intervals that are more like supra-threshold stuff?
Am I just pointlessly working at levels above VO2 max or will these efforts still have a benefit on VO2 max?
Also, I’m sure I read somewhere that, with VO2, you just have to go as hard as you can for the duration of the interval. I am still finding the RPE feel of these harder efforts, and often go out hard initially and then drop off and settle for the remainder of the interval, but not dropping off as far down as the power level that TR suggests. What I mean is, I am still easily hitting the power target prescribed, but it isn’t in a nice flat line like it is on the trainer - it has a spike at the front. Is this initial spike a bad thing? I am hoping it will go away when I am better able to get my RPE right at the higher power stuff. But in the meantime, is it just causing me pointless stress rather than aiding anything?
If I am outside and have to ride a bit between blocks of intervals, is this a problem? Like today I stupidly forgot to put the bottle on the bike so I had to ride and find a water spring to drink from halfway through the workout. This gave me some unstructured riding between blocks 1 and 2 on the intervals. Will this affect the workout significantly, or does it not matter as long as I hit the power targets on the intervals?
Finally, intensity factor - today I got a 0.96 intensity factor but I literally have no idea how that is calculated because it definitely did not feel that intense. Obviously the short efforts did, but the rest of it was faffing/recovery. The only thing I can think is maybe because of the unstructured riding in the middle that bumped this up a bit?
