Following this thread it seems like you started SST work in early January. I wouldn't jump to L5 or higher training after only a month of aerobic base building. Maybe you've been at it longer than this thread indicates, but as important as high end work can be for crits, you want to build that high end work on top of a strong core of aerobic fitness.
One way to start prepping for the acelerations and jumps that you'll get in crits while still building your aerobic engine is to introduce a day of microintervals. There are different flavors, but in general ride a sustainable SST pace (Tempo through mid SST) and do a seated jump for 10-15 seconds every couple of minutes. At the end of each seated jump go right back to your Tempo/SST pace as quickly as you can. Do this in 20 to 30 minute blocks just like you'd do your SST efforts. You'll end up with an AP in L4 but with frequent acelerations and recovery in Tempo/SST. It won't take long to figure out how to manage the intensity of those seated jumps, go too hard and you won't last long but they should focus on quick aceleration and snap.
Quoted post said:...Should I start mixing in some L5 and L6 days into my February training? I was thinking of shooting for 4-6 X 5 minute intervals for L5 and 4-6 X 1 minute intervals for L6.
I wouldn't unless your base is deeper than this thread would suggest. And I wouldn't jump to both weekly L5 and L6 days at the same time. Those are hard efforts and will take some getting used to. They'll also cost you training volume or CTL in powerspeak as it's hard to rack up as much quality time in the higher levels.
If you've got the base then I might add an L5 session early in your training week starting in mid February. I'd also try to extend one Tempo or low SST session later in the week to offset the reduced TSS that generally comes with a move to higher end work. L6 work can come closer to your events as anaerobic fitness tends to train up pretty quickly and if associated with a decrease in overall training load can bring about fitness peaks. Best to have those peaks correspond with your races and not come too soon. You might find that the races themselves provide plenty of L6 work with less mental effort than making yourself suffer during 1 to 2 minute all out intervals.
One strategy for a 6 week series is to hit the early races with enough fitness to finish the races and at least ride with the field and then to build throughout the series. If you started your focused training in early January then this would be a good strategy for a spring series and set you up better for races later in the season than trying to cram for peak fitness in a short time.
Good luck,
