I'm a Mainiac

Last Saturday dawned as a beautiful if chilly day in Portland Maine. I was up around 6:15 AM (45 degrees C) to put my triathlon gear into the car and by 8 AM I was on the road to beautiful Biddeford for the first ever Mainiac triathlon.

I put all my stuff at the transition area and talked with some other folks before the race started. As I wanted to keep my blood sugar under control, I'd decided not to eat any carbs for breakfast and I reduced my basal to 50% for 2 hours about 2 hours before race time. Thanks to my Dexcom, I was able to watch my BG creep up until it was around 215 before the swim started. So I ended up taking a small bolus before removing the pump and zipping into my wetsuit.

Then off to the beach with other triathletes to wait for the pep talk before race time.



After a recap of the rules and a lovely rendition of The Star-Spangled Banner, we all walked down the beach to the official starting point.

There were four swim waves separated by 3 minutes. I was in the third wave, for the over-40 men. So we got to see the first wave rush towards to the water while we waited nervously. As someone said, it was a beautiful photo moment.

After a few minutes of smalltalk it was our turn to rush towards the cool blue Atlantic water.

Let me just say that the swim was a lot harder than I'd expected. Although I'd done several miles of swim training overall, the combination of the colder water and the slight current made this part a lot more difficult than I expected. So I made slow progress in completing the 1/4 mile, and I was fairly worn out when I did make it back to the beach. (Note to self, I need to learn to do front crawl!)


Then it was a 100 yard dash up the beach to the transition point. I dried quickly and got my pump back on as I changed into my bike gear. My blood sugar had gone up slightly, so another minor correction and a quick drink of some electrolyte mixture before getting on the bike.




The bike ride was 14.7 miles and it was really flat with nice scenery all along the way. Much of it hugged the coast and the breeze was gentle enough that it neither helped nor hindered. But I did notice my legs cramping up during the last few miles. I stopped twice to get a look at the Dexcom and drink some extra fluids, and my blood sugar was finally getting closer to a normal range.

Getting back to the transition area, my blood sugar was around 150. A relatively quick change into running shoes and top and I was off on the last 3.2 miles. Now the weather was a good deal warmer, so no long sleeves were needed.

One of the things that the run (really an extended jog/walk) taught me was just how hard it is to do even a short triathlon like this one. I appreciate much more how hard an Ironman event must be, especially with diabetes. By the time I got to the first water stop, my blood sugar was dropping faster so I drank some energy drink and walked on. At some stage I passed the 1-mile marker and was very disappointed that it didn't have a big 3 on it!

But I made it all the way home to the big timer and a "Bernard Farrell is now a Mainiac" announcement from the DJ.

The organizers did a great job. There were several folks from a local college who were training as masseurs, so I managed to get some relief for my brick-like calf muscles. That helped a lot.

Total time was a big disappointment, a little over 2:07. But looking at the biking time, I realize that it was the tiring swim that really messed me up. During the entire triathlon my blood sugars ranged from 230 to 130, which is a little high but a great range overall.

The good news was that I finished the triathlon and was still able to walk/get around for the rest of the weekend. Along the way, thanks to many friends, I managed to raise over $4,700 to support Dr. Faustman's research into a type 1 cure. (And I'm happy to take more donations if you're feeling generous.

By a strange coincidence I met Dr. Faustman on Monday, when I was giving another blood sample for her research. The news there is all great. In August her team published a paper showing that their approach kills the bad T-cells that destroy our insulin-producing beta cells. They also showed that this approach did not kill any important cells in the healthy blood samples. To my mind, that's important proof that this is unlikely to produce unwanted side effects.

Dr. Faustman also told me that she was interviewed recently and asked which venture capitalist was funding her research. She told the interviewer that it was being funded by lemonade stands and bike rides. He was amazed that this level of research could be funded in that way.

Those of us in the D-community understand the importance of this research for ourselves or our children. And we're doing whatever we can to keep it going, though it seems like an impossible task at times.

Thank you all for your support in my triathlon attempt. Next year (hah!) I plan to get to the finish line much more quickly and in better shape.

Swimming with the Dexcom CGM

As I prepare for my fund-raising triathlon, I've been doing a lot of swimming. One problem that I had to solve was how to swim and monitor my blood sugar at the same time.

My Dexcom receiver has to be within 5 feet of the sensor/transmitter. That doesn't work when I'm swimming 1/4 or 1/2 mile distances. While the sensor/transmitter is waterproof, the receiver isn't.

I read somewhere about Aquapac and it's line of waterproof cases, so I measured my Dexcom receiver and ordered their mini class case.

Picture of a Dexcom receiver beside the Aquapac caseWhen it arrived it certainly looked big enough for the Dexcom receiver. But when I tried to put the Dexcom into the case, the face would bind to the plastic. So I took a small index card, folded it, and slipped it into the case first. Then I could easily get the Dexcom receiver in place. I use the index card again when I want to get the receiver back out.

Inserting the Dexcom

Aquapac4When I'm swimming, I use the cord that comes with the Aquapac. I can swim with the cord around my neck, and provided I keep it on the same side as the sensor, I get great readings during the swim. I can also see the values while I'm in the water.

For my triathlon, I leave it in the case until the end. That way I don't have to worry about damaging the receiver due to sweat or rain. I've used this case on three long swims (> 15 minutes in the water) and it's worked perfectly.

My upcoming triathlon

If you're a regular reader, you'll know I've been offline for a few weeks, this was for good reasons. We visited Ireland for a big family reunion and had a wonderful time.

I'm finally back on East Coast Time, but still missing all of my family in Ireland (including my darling grand-daughter) and the wonders of beautiful Kilkee in County Clare in Ireland. I promise to post a few pictures in the next fortnight or so.

In the last two years I've raised funds for Dr. Denise Faustman's research into a cure for type 1 diabetes. This year, the Bike the Miles folks don't have an event as they their fund-raising goal. So I've been preparing to take part in a triathlon and use that as a fund-raising opportunity. For me, that's a big challenge, even if this isn't an Ironman-type triathlon.

So on Saturday September 6th I'll be taking part in the Hyannis Sprint 2 Triathlon on Cape Cod. The triathlon has a quarter-mile swim, 10 mile bike ride and 3.5 mile run. If you're going to be there, I'd love to say hello.

I'd like to challenge you to sponsor my triathlon so I can raise more funds for Dr. Faustman's research. In previous years I started fund-raising in the spring, so I know it'll be a stretch to get more than $3,600. But that's my goal for this year: $100 for each year I've had type 1 diabetes.

I'll do the sweating and you just have to write a check of any size. (If you're a US taxpayer the amount is a charitable donation.)

Your check should be made out to Massachusetts General Hospital with Dr. Faustman Type 1 research in the memo field.

You can either send it to me at my P.O. Box
    Bernard Farrell
    P.O Box 937
    Westford, MA 01886

Or you can send it directly to the hospital at
    The Massachusetts General Hospital-East
    Attn: Lynne Murphy
    Building 149, 13th Street, Room 3602
    Charlestown, MA 02129

If you're doing this to sponsor my triathlon, please send me an email (bernard.farrell@gmail.com) letting me know how much you sent to Mass. General so I can track the level of sponsorship I get.

As always I'm grateful for any support I get in this effort and I do plan to have a page acknowledging all the support I get (let me know if you don't want your name on this page).
