MarathonBQ – How to Qualify for the Boston Marathon in 14 Weeks -

Hello my friends.  How are you?  How’s your summer going?  Welcome to our little endurance sports podcast that we’ve been doing for more than a decade, welcome in fact to episode 4-371. 

We have a good show for you today.  I’m quite satisfied with this one.  Good content.  Good writing.  Good audio.  As they say “Even a blind squirrel finds an acorn every now and then.”

Today we have an interview with Arnar from Tymewear.  I’ve been advising Arnar on his start up. Hopefully I’m doing more good than harm. I went in to see him this week.  He’s working out of seaport area of Boston.  There’s a lot going on down there.  That’s the place GE is building its new HQ.

Since I was in there I recorded the interview in this show.  Interesting stuff.

In section one I have a useful instructional piece on smoothies! Yes smoothies!

In Section two I have finally wrote down a story that has been bouncing around in my head for a good 5+ years.  Working with Arnar finally shook it loose.  As you know I’m a big science fiction fan.  I was able to combine Science Fiction and running into a story!  How about that?  And no zombies required.

Nothing unusual to report on the training front.  Last week was a down week and I’m ramping it back up this week.  Still have to go out tonight and do a hill workout when it cools down a little.  I had to sleep in a bit this morning.  I’ve had some sort of allergy or cold this week.  I noticed my HR was high on Tuesday when I did my morning 10 mile trail run.

I gave blood on Wednesday and I’ve figured out how to pass all the hurdles.  I mentally raise my heart rate up into the 50’s by thinking about fighting and sprinting and finishing a race etc. – and that gets me by the low heart rate constraint.  Then I took a tip from one of my running buddies and pounded water all day going in so I would be dehydrated and sure enough the blood came squirting out!  No problems. 

I managed to get down to my house on the Cape and spend a couple days cleaning.  I did ride my bike over to the ocean and go for a snorkel.  Got some sun. 

My tomatoes are coming in but the real bounty is in the wild black raspberries outside my garden.  There are so many they are falling ripe to the ground.  I go out every couple days and pick a quart or so but I have to tamp down my compulsion to pick all the ripe berries because I would be out all day.

I told Teresa that we are disturbing the natural ecosystem by pillaging all the wild black berries.  Those berries want to be eaten by wild animals who then spread the berry seed with a bit of fertilizer throughout the neighborhood.  I told her if we eat the berries that only way we can save nature is to poop in the woods. 

She and I were all set to climb Mt. Washington last weekend but when I checked the weather it said it was 34 degrees Fahrenheit, 100% rain and hail with 40 mph winds on the mountain.  I’ve had my fair share of adventures but I told her that didn’t sound like something we should willfully walk into. 

On with the show.

I’ll remind you that the RunRunLive podcast is ad free and listener supported.  What does that mean? It means you don’t have to listen to me trying to sound sincere about or Audible.. (although, fyi, my MarathonBQ book is on audible) We do have a membership option where you can become a member and as a special thank you, you will get access to member’s only audio. There are book reviews, odd philosophical thoughts, zombie stories and I curate old episodes for you to listen to.  I recently added that guy who cut off is foot so he could keep training and my first call with Geoff Galloway.   “Curated” means I add some introductory comments and edit them up a bit.  So anyhow – become a member so I can keep paying my bills.


The RunRunLive podcast is Ad Free and listener supported.  We do this by offering a membership option where members get Access to Exclusive Members Only audio and articles.

Voices of reason – the conversation

Arnar Larusson

TymeWear -

There are a lot of products in the sports tech and wearables space, what led you to start working on the TymeWear solution?  What’s the origin story?

  • I was developing prosthetics, orthotics, and exoskeletons before co-founding Tyme Wear. Those experiences taught me how valuable accurate insights about our body can be, and that the worlds of soft materials and smart electronics could be merged in a very interesting way. That through some innovation, we could create products that have technology that is transparent to the user, but that delivers real value towards improving our health, wellbeing and performance.


How is this different than my FitBit or Garmin Watch?

  • Our product is a t-shirt. We wanted our technology to blend into the things an athlete would be wearing anyway. We collect physiological data that is as accurate as medical grade equipment. The more accurate the data, the more actionable and useful it becomes.


Why do I need this?  As an endurance athlete, why do I care?

  • For any athlete that wants to improve, it helps a lot to know your current endurance limit, and what your potential is. We measure ventilatory threshold (VT) and VO2max. The VT is your current endurance limit, improving your endurance improves your VT. Your VO2max tells you how deep is your well, your potential. Knowing these two things informs exactly how hard to push, and helps you define and reach your goals.

Talk through the difference between HR/ Respiration, effort, training zones., MaxVo2

  • Respiration is directly correlated to your effort level. It is also a measure of your physical limits, your VT and your VO2max. HR by comparison is a great relative measure of effort, but because it has so many compounding factors like stress, sleep quality, to name a couple, it can be very unreliable.

Who is your target market?  

  • We are for dedicated athletes that want to train to the limit of their ability, value accurate information on their workouts, but struggle with knowing where their limit is and how to train to it.

Where do you want to be in 5 years?

  • Working hard :)

If you had to say what your mission is what would it be?

  • To make our bodies accurate data available and actionable to anyone, anywhere.

What have you learned so far in bringing this product to market?

  • Working at the intersection of industries is rewarding but challenging. We work with apparel designers, electronics manufacturers, athletes, coaches and medical professionals. Each one has their own language and frame of reference. Our job is to be in the middle and make sense of it all.

What kind of help do you need from our audience?

  • We are looking for beta testers that are dedicated endurance athletes. Meaning anyone that goes out at least 3 times a week. We want people that are curious about knowing their current endurance limit. People that are skeptical about the current way of tracking performance. People that can help us learn and improve our product.


Section two – Robo-Running  -


OK my friends, you have run in your high-technology smart garment to the end of episode 4-371 of the RunRunLive Podcast. 

I’ve got a few things lined up for you.  First is this guy I interviewed that is running a marathon in every national park in the US.  You may have seen him in that running magazine this month – they are always copying me. 

I’m also trying to get the RD for the Portland Maine marathon on for a debrief.  I’m going to run the race on Oct 1st.  I’m in good enough shape, I need to tune up and lose a little weight, but I’ll race.

Before that I’m going to run the full Wapack Trail Race again this year.  Which is an 18 mile technical mountain race that my club puts on.  I think we’re doing a relay this year if you want to come up and do one way, which would be 9 miles. 

And, of course we are looking ahead to December 31st again this year for the Groton Marathon. 

I’m going to swear a bit in the next few paragraphs if you want to plug the kids’ ears. 

I was talking with a friend of mine last week.  He was supposed to go on vacation but his wife got sick and I could tell he was mad about it.  He didn’t ask me for advice, but I gave it to him anyhow.  Very simple advice.  Don’t be an asshole. 

We get all cranked up inside our own heads and start acting like we’re right and someone else is wrong.  It’s all ego.  We construct these stories of how we are long suffering and put upon.  I know I do it.  And then we lash out.

Do you know what the other person sees?  They don’t see any of that stuff in your head.  They just see you lashing out.  You just look like an asshole. 

My wife called me last night.  She wanted to know what I cooked for dinner.  I’m thinking to myself “What the hell? What am I your cook? I’ve got a cold.  I’ve got work to do. What have you done for me lately?”  Then I realized that she didn’t know any of that and it didn’t matter to her.  So I chose to not be an asshole.  I got some food from the market and cooked dinner.

I was standing at the fish counter in the market down on Cape Cod.  There was a young couple there fighting over whether or not to buy mussels.  She wanted mussels.  He kept saying “Buy the mussels if you want” but he was really saying, “Mussels?  What are you stupid or crazy?  Why do I put up you’re your insufferable crap.  Mussels my eye.”: 

When he finally wandered off and left her standing there, contemplating the mussels, I leaned in, smiled and said “Tell him to stop being an asshole.”: 

That’s it.  Secret to life. Don’t be an asshole.

Inside your own head.  Let it go. 

I’ll see you out there.
