Dirt and pavement

MTBs: driving skills, high-end power, flow. Yin. Often fun over suffering.
Road: Team work, patience, lightness, tempo-power, luck...and suffering over fun. Yang. The giro this year just about epitomizes the quintessential essence of the insane difficulty of road racing

Stand Up to Cancer

Lots of people out there are burnt on cancer charities.

Sometimes it's hard to tell where their money goes.

Stand Up to Cancer, has a pretty amazing track record of helping to fund multi-institutional initiatives that are clearly getting money into the hands of researchers working to understand cancer and save lives. And their website is 100% transparent.

Cycling and sun exposure

I haven't been blogging much recently...bike racing and writing about it definitely qualifies as a hobby, and writing on this blog about bike racing just hasn't fit into the 168hours of the week recently.

Bringing together my own experience with cancer, my training as a physician scientist working on cancer, and my passion for cycling is basically the focus of this blog this year. With that in mind, I thought I'd post on something that doesn't get thought about enough in cycling; our exposure to the sun.

I've been really interested to see that a few companies are starting to manufacture UV protection into the spring/summer cycling apparel. I think it is incredibly important to support this.

Here is an interview with a dermatologist from Stanford about 'facts vs. fiction' associated with sun exposure:
"What does the layperson need to know about UVA and UVB rays? 
Ultraviolet (UV) radiation rays are responsible for sunburn, skin cancer, and “photoaging” (accelerated aging of the skin).  Approximately 95% of UV radiation is comprised of UVA type rays, which are strong all day and all year long. The other 5% are UVB type rays, which  penetrate the skin less deeply but are 400 times more intense in the summer and in the mid-day hours between 10 a.m. and 4 p.m. UVB rays play the largest role in causing sunburn and skin cancer, although UVA rays have more recently been linked to skin cancer and photoaging.

Who is at risk for skin cancer?
One in five Americans will develop skin cancer in their lifetimes, with the nonmelanoma skin cancer types (basal cell and squamous cell carcinoma) predominating.  Melanoma is the most deadly form of skin cancer, accounting for only 4% of cases but over 80% of skin cancer deaths. People with fair skin (skin types 1 and 2 on the Fitzpatrick skin phototype scale) and those with increased numbers of common and atypical moles, sun sensitivity or family history are more likely to develop melanoma. Older men have the highest incidence and mortality rates from melanoma, although the number of new cases in young women is on the rise — likely related to tanning bed use.

Buying sunscreen can be so confusing.  What should I look for?
The new FDA regulations have resulted in a big change as well as relabeling of sunscreen products, which must filter out the entire range of UVB and UVA wavelengths to be labeled as “broad spectrum.” Effective UVB filters have been available for many years and are measured by the sun protection factor (SPF). Full UVA filtration has been harder to achieve, and in the US, sunscreens that contain a chemical called avobenzone that is photostabilized with octocrylene provide the best UVA protection. Other UVA filters may be more effective but are not yet available in the U.S.

What is the biggest mistake people make with sunscreen?
Insufficient application is the most common mistake. Consumers use only about one-fourth to half of the sunscreen they need to achieve the SPF level that is actually contained in the product. For this reason, it may be more useful to apply a higher SPF-containing sunscreen (30 or above) or simply increase the amount you are putting on your skin. The key is finding a brand you like and using it regularly. A good rule is to use about 2 to 3 tablespoons for your body and 1 tablespoon for your face and to reapply every 2-4 hours. Remember, there is no such thing as a waterproof sunscreen, although sunscreens will soon be rated as either water resistant or very water resistant depending on how well they maintain their SPF level after water immersion. You can apply sunscreen just before you go outside, but you don’t want to put it on and jump right in the pool.

What about Vitamin D exposure?
The Vitamin D controversy has been overblown by the tanning industry, with some companies suggesting that seeking a tan (by artificial or natural UV light) is good for you. Incidental sunlight is likely adequate for sufficient vitamin D levels in most fair-complexioned individuals. Vitamin D supplementation is definitely safer than exposing yourself to excessive UV radiation to increase you blood levels of vitamin D, and there are guidelines for how much vitamin D to take published by the Institute of Medicine.

How do you convince the skeptic that sunscreen is worth the effort?
In 2010, the first prospective randomized trial was published that showed that daily use of sunscreen reduced the risk of melanoma by 50% compared with optional use of sunscreen. The benefits of sunscreen and sun protection in general (including avoidance of mid-day sun and tanning practices, and wearing hats, protective clothing and sunglasses) are well-established in terms of reducing the photoaging process and preventing skin cancer."

Training/riding as a parent

I've pretty much built my whole life the last couple of years on mechanisms, practices, and schedules that allow different hats to be worn: Dad, friend/husband/supporter to an almost doctor, cancer researcher, bike rider, and doctor-in-training.

This is a great article about having kids and riding: http://www.cxmagazine.com/coaching-corner-guilt-training-kids-time

One of the struggles I've found myself in regarding the Columbia cycling community, is not making it to many group rides. Most are scheduled around 8-5 type jobs, which unfortunately doesn't apply too me. Plus, from about 4:30 until 8:30 every night, I'm busy wearing an apron.

Suffering

I haven't really known what to blog about recently.

Things have been extremely busy with family (my wife's currently working extremely long hours at the hospital...often there at 4:30 or 5am and not home til after dark), research, some consulting I'm doing for an oncology firm, and of course riding.

Last weekend, I returned from a 3hr ride simply ecstatic because I had set a goal for myself regarding not shifting and managed to feel good the whole ride. It's those little, somewhat arbitraty bench marks that I find entertaining. Although I've been opposed to Strava for a while because it seems silly to race virtually, I started using my account a couple of weekes ago so that I can record my volume for the year. Anyway, after this ride I saw that my legs had produced more kJ's in 3hrs then a friend of mine had done in a 6.5hr century. I didn't really feel ecstatic or victorious, or somehow superior in that comparison...it's funny, but competition on the bike for me is much more of an internal, i.e. introverted, process of pushing myself to do things as opposed to me wanting to beat others. I've spent a lot of time thinking about why a ride and why I race and one conclusion I am absolutely certain about is that I don't do it to win or beat others. I do it to challenge myself and break boundaries.

I train on the bike because, quite simply, it (I'm paraphrasing something I read from strength coach Charles Staley) it restores my confidence in the value hard work. Exercise is of course healthy, but I have no delusions that health is the output of the input (physical, emotional, social, financial) I put into cycling. So why do I give it so much? I bleed over it. Why do I aleter and orchestrate my career and lifestyle so that I'll be able to ride and race?

Part of it is that I've always been this way. Speed skating as a kid. Then bikes, then rock climbing, and then back to bikes again. And it was during rock climbing, where pseudo-taoist-buddhist philosophy runs deep, that I think I learned to love and desire the internal process of trying really, really hard to do things...to move, to feel my body, and connect to the earth and feel the elements.

Competition is fun, but self-competition is what drives me. I hate to sound corny, but cancer has deepened this sort of self study, journey, quest, etc. Given the state of my lungs and history with thyroid cancer, pushing myself on the bike, seeing what I'm capable of, somehow provides meaning in all of this.

I'm really excited for this next year. We're going to be super busy...I hope to finish up my PhD by next spring, then will be at a crossroads to decide if I should then try and do both medicine and science, or just one. In the meantime, I'm going to do some NUE racing this next year on the mountain bike; sometimes I set out on my bike with the knowledge that I'm going to suffer. This is one of those cases....but I can't freakin wait!

Cohutta 100 is first in the smoky mountains on April 27th.
