No. 54: Spring Training

27 March, 2012 1:58 AM / Leave a Comment / Gene Dan

Hey everyone,

I didn’t race this week, but it looks like the rest of my teammates had a lot of fun so I kind of regret not going, but I did get some good training in despite the lack of good weather/suitable courses. On Tuesday, it rained, and on Thursday through Sunday there was an art festival at Memorial Park, so the Picnic Loop was closed to bicycle traffic. This means that I couldn’t do my structured intervals as planned, but I went out anyway and rode from Memorial Park to Highway 6 and back again, keeping the heart rate at about 160 bpm and the average power above 200 w.

On Saturday, I drove back down to Clear Lake to ride with the folks at Space City Cycling Club. I really looked forward to this ride since I hadn’t done it since I started racing this year. In my opinion, it’s one of the best training rides in Houston since some of the best cyclists in Texas ride down there on weekends when they’re not racing. The pace usually speeds up to 30-34 mph at the beginning, and I almost always get dropped before I hit FM 517, but this time I managed to stay in contact until that point. I felt really good until I got boxed in by a bunch of people who couldn’t hold the pace, but I’m pretty sure I could have held on if I had paid more attention. This is actually a really important factor in racing because you need the ability to accurately gauge other riders’ fatigue in critical situations so you know whom to follow and whom to avoid. I tried chasing in vain at a pace of 32mph, but after I got tired I decided to work with a chase group and I did some long pulls of 2-3 minutes at 300 watts each. After 1:30:00, I measured my average power at 220 watts – about 7 w more than I had done at Fayetteville. 7 watts doesn’t sound like a lot, but it could mean the difference between hopelessly dropping off the back and staying in contact until the finish.

Coming back from the halfway mark, I felt fantastic. I kept doing the long 300 watt pulls at around three minutes each until I got a flat tire. Thankfully, a group of three guys helped me fix the flat, but 10 minutes later, one of the riders who helped me also flatted. It took a while for me to feel comfortable again, but at the end of three hours I averaged 207 watts – that’s a higher wattage over a longer period of time than both Walburg and Mineral Wells. I’m feeling optimistic, considering that this was just a training ride, and that I only averaged 173 watts on the same ride 2 months prior.

Average power isn’t everything, however. Sometimes the ability to maintain a high output for short periods of time during the right moments matters more. On the other hand, if you can maintain a greater number of peaks for longer periods of time, you won’t have to worry so much about timing your efforts correctly. In reality, the best racer will have both a superior level of fitness and an acute awareness of the overall racing situation. The physical fitness comes from good preparation, but the ability to time your efforts correctly allows you to conserve energy for those crucial moments when the pack surges. Without racing knowledge, your physical ability will never manifest itself during the moments that matter. I think that’s what separates the winners from those who are strong but not smart, and vice versa. I don’t consider myself to be strong or smart (yet), but I feel that I’m getting better at both and I’m looking forward to racing at Come and Take It this weekend. My finishes during the last two race weekends were really demoralizing, but when you’re down, you really have to keep at it – you have to take a moment to reflect on what went wrong, and then do the things in training that you weren’t able to do before. One main weakness in my training is that I don’t have specific goals – when I train, I come in with the attitude, “let’s do these intervals and see what happens,” but the problem is that it’s not focused or goal-oriented. Tomorrow, the weather looks good and I aim to do two 4-lap intervals at 170 bpm, while reducing the amount of rest between them from 4 laps to 3 laps. It’s harder than what I’ve been doing previously, so it’s definitely a step in the right direction.

No. 51: La Primavera Lago Vista 2012 – Race Report

6 March, 2012 2:46 AM / 4 Comments / Gene Dan

Hey everyone,

Lago Vista didn’t go well. The race took place over the course of two days. On the first day we went clockwise around a 5.5 mile loop, 75% of which consists of a gradual climb and 25% of which consists of a steep descent. On the next day we went in the other direction so we’d have a really steep climb but a long, gradual descent. In short, I dropped quickly on both days, though I stayed in contact for a longer amount of time on the second day. I don’t want to go into too much detail since not too much happened, so let’s just take a look at what little data I gathered to see what went wrong during the race.

Preparation

Every Tuesday and Thursday, I wake up at 5:30 AM to do intervals on the Picnic Loop at Memorial Park. I start out doing 8 intervals of 1 lap each on the first day, then 4 intervals of 2 laps each on the next day. As the days go by, my schedule goes as follows:

8 intervals 1 laps each
4 intervals 2 laps each
3 intervals – 1 interval of 2 laps + 2 intervals of 3 laps each
2 intervals 4 laps each
2 intervals – 1 interval of 3 laps + 1 interval of 5 laps
2 intervals – 1 interval of 2 laps + 1 interval of 6 laps
2 intervals – 1 interval of 1 lap + 1 interval of 7 laps
1 interval of 8 laps

After I complete the cycle, I start over again. On Saturdays, I usually do a 3 hour group ride. I haven’t planned out what to do on Sundays. So far, I started doing 2×20 min. intervals, aiming to reach 2×30 min. Here’s some data from the training session I did the Thursday before the race, along with the splits below:

Here’s an 8x interval training session from the previous month:

Isolating the intervals gives the following comparison:

Which shows that after 1 month, the average power increased about 9% for each lap.

Now, I felt pretty good about that because it shows that I’ve improved over the month. Unfortunately, after putting in an easy effort at Walburg, I underestimated the difficulty of Lago Vista…

Lago Vista – Day 1

As soon as the race started, I felt like I was trying really hard the whole time at the limit. The data above confirms it – the black line marks the point at which I dropped from the main pack. For the brief time I stayed in contact, my heart rate was fluctuating between 166 and 172 bpm, and I took several efforts at 400-600 watts.

Lago Vista – Day 2

On the second day, you see a similar pattern, with my heart rate barely going over 172 bpm before I dropped. Now I think I know why I didn’t do very well during this race with respect to my preparation – I don’t train like I race. Shama racer Ken Day took a look at my interval data (from the first picture) and told me that I took too much rest between my intervals, and advised me that it would be better to not let myself rest completely before starting another. I agree – during a race, after you or someone else attacks, you never really get the chance to fully recuperate. Your heart rate will fall a little but it will still stay at a level where you’re still trying hard. I took a look at Said’s data, and he managed to average 166 bpm for about 2 hours. I can hold 166 bpm for extended periods of time, but during training, I’ll hold it at 166 bpm without going over 170 bpm – ever. However, during the race, I will certainly have points where I have to go over 170 bpm, as demonstrated above, so I need to somehow incorporate those efforts as I haven’t intentionally gone over 170 bpm during a training ride. In terms of wattage – I mainly try to hold it steady at 250 watts but I don’t have any training sessions where I try to hold a higher wattage, say 300-600 watts. In short – I haven’t done any high-intensity (as in not just higher than normal, but really high) or max efforts so I need to do them since that’s what I’ll be doing during a race.

So, for this Thursday, I plan on doing 8×1 minute efforts. I don’t know how many watts I can hold during that time so I’ll just go as hard as I can and use the data from this session as a benchmark against which I can compare future sessions. After that, I plan on reducing the amount of rest between intervals, and maybe during my 30-minute intervals I’ll intentionally go up to 800 w and then back down to 250w to simulate racing situations. Anyway I’ll be joining a group ride tomorrow to give myself a mental break before I start doing intervals again.

Even though I didn’t do well last weekend, I don’t regret going at all. I had a lot of fun and made some new friends, and learned a lot. Special thanks goes to our teammate Jennifer Wagner for setting up the condo at Lake Travis.

Notes:

I’ve finished my European History book last week, and I just finished reading Kingpin yesterday. I’ve since started reading a Sociology textbook, which should keep me occupied for the next two months. After that, I’ll read The Cyclist’s Training Bible and Training and Racing with a Power Meter, which should eliminate a lot of the guesswork in setting up a proper training schedule.
