Three weeks post-Ironman and still trying to find my stride, so just filling my time with the things that bring me joy 🐕🐶🍩🚴🏼‍♀️⛰️👯‍♀️🥾

All summer I struggled to find my groove and I felt stressed and pressured to get to the starting line of a race, to have something to show for the season. Kalmar was very last minute. With only 4 “good” weeks of training leading into the race, I figured I’d take the risk and see if I could put something together, showing up to the starting line barely in one piece. I don’t regret the experience but I’m also not sure it was worth all the stress and the money.

I’m not sure where this leaves me for the rest of the season. I’m taking a bit of a break from structured training but still training on my own accord. Trying to find the joy and excitement in pursuing this sport that I once had. I know it’s still there. I think I just need time.

If you’re looking for a destination Ironman and one-of-a-kind experience, put Ironman Kalmar on your bucket list 🇸🇪

We were blown away by how the entire town came together to support the race and all of the athletes. I’ve never experienced anything like it in the US. We were welcomed immediately ,and everyone we had the pleasure of meeting was so kind. I rate races based on the people I meet, how easy it is to swim/bike/run before the race, and the race experience itself.

The race itself was spectacular. The swim had everything, from big ocean chop to smooth sailing through a canal lined with spectators (spectathletes) screaming and cheering.

The bike course was split into two sections - the island Öland, and the mainland. The flat farmland of the island was sprinkled with Swedes sitting outside their houses eating breakfast around a huge spread of treats and cheering every time we passed. The course was flat, but the wind was something fierce 🌬️

Once back on the mainland, we had 50k of rolling technical terrain through the gorgeous Swedish countryside (this was my favorite part!).

The run was incredibly dynamic with concrete, pavement, dirt/gravel paths, cobblestones, and even a section on a track, all lined with spectators screaming and cheering. The finish line was one to remember, and one that makes you remember why you do this crazy sport in the first place.

Tack så mycket 🙏🏼 We’ll be back!

Ironman Kalmar - a race experience to remember ✨

A couple firsts for me yesterday..

First time racing in Europe! (Kalmar is the perfect fave venue)

First time leading a group out of the swim (probably one of the coolest swims I’ve ever done, navigating all over the harbor, under bridges, around rocks)

First time getting my period in the middle of a race (halfway through the bike 🫠 and then the subsequent cramps just zapped the power from my legs the rest of the day.)

First time doing an Ironman marathon without ice on the course (I rely, maybe too much, on the ice to keep me cool but also hydrated between aid stations. Not having it was a struggle and my legs just locked up from cramping with 10 miles to go.)

Ironman Kalmar is magical though. If you’re looking for a destination race, I highly recommend. The entire (literally entire) town comes out to support (swipe to see the finish line last night).

Grateful to be here and share these moments with 🫶

Ironman Kalmar tomorrow! Race goes off at 6:45am Sweden time (which means most of y’all will be sleeping for almost the entire race 😄). No live coverage but I’m bib #14 on the Ironman tracker app. Excited to explore the Swedish countryside while racing one of the strongest women’s fields Kalmar has seen! See y’all on the other side!

I did my first Ironman when I was 25 years old. I was 9 months post-ACL reconstruction and my surgeon told me in my first pre-op appointment that, sure, I could do an Ironman in 9 months! My rehab was less than stellar and my PT didn’t seem to care about me or my goals. I ended up taking the rehab protocol and doing my own thing after two months (do not recommend doing this).

I remember starting the Ironman marathon after the hilly Mont Tremblant bike, and running felt natural. I ran 3:57 for my first Ironman marathon, when I had never even broken 4 hours for an open marathon. I knew in that moment that this was the distance for me.

I didn’t have a coach. I had reached out to my local tri club at the time to help with a training plan because I didn’t know what I was doing. I didn’t get much help, so I found a free 16-week Ironman training plan in Triathlete Magazine and used that.

I averaged about 10-12 hours a week of training. Four weeks out from the race, I did a 100 mile ride to Bear Mountain in NY fueled with rice cakes from the Feed Zone Portables cookbook, and a 20 mile run off the bike drinking chicken broth (literally didn’t know what I was doing 😂). Then basically tapered for a month lol.

I didn’t have much support from those closest to me at the time. I felt alone in my journey but I was intrinsically driven and wanted it badly. After I crossed the finish line, the motivation to see where I could go grew.

It wasn’t until I actually had money to hire a coach and get a decent tri bike (many years down the road) that I started to see big improvements.

I’m proud of how far I’ve come, even if it’s taken me longer than the typical amateur-to-pro pipeline. As I get through my last key sessions before Ironman Kalmar, it’s not lost on me how lucky I am to be able to race at this level across the world, with the best support and the best sponsors.

This will be my first race in Europe and I’m so excited for the chance to do my favorite thing and explore a new part of the world. The gratitude runs deep.

Swim - 13,000 yards, 3 hours
Bike - 246 miles, 12.5 hours
Run - 32 miles, 4.5 hours
Strength - none other than light activation before sessions.. had to get my muscles to bounce back from the race

Coaching work - 5 hours
Puppy playtimes - numerous 🎾
Normatec sleeves - 4 hours
Highest Garmin Sleep Score - 87

Finished my last big session yesterday feeling 💪 All that’s left is to taper and sharpen up.

I learn a lot about running health from my own running journey but also from my patients, and seeing the same patterns and mistakes lead to the same outcomes. The biggest thing I’ve also learned is that injuries are virtually impossible to prevent in runners due to the highly repetitive and stressful nature of the sport. The best thing we can do is be smart in our training and prep to give ourselves the best possible chance to stay healthy. Questions about any of these specific slides? Drop a comment 👇performance

A solid day out there at Boise 70.3, even if my placing doesn’t reflect that. Came and accomplished what I set out to do and proud of my body for showing up for me (finally!).

Swim: a meh experience… the water was super choppy. I found myself with a group of girls but the gal leading had some sighting issues and it seemed like we were switching directions every time I looked up to sight. We almost missed the final turn buoy but and I caught it last minute and left the group to head the right way. I believe this was my slowest 70.3 swim ever (and I also had almost 2600 yards with our short run to transition 🤦🏼‍♀️).

Bike: Legs heavy from the start but I reminded myself that we did not taper for this race and this was to be expected. Power was actually solid, but I rode the entire 56 miles solo (and slower than most of the other women). Was a little sad to see the other pro women riding together during some of the out and back sections and wished I could’ve been there with them.

Run: Legs felt good immediately off the bike, better than they have in a long time 🥹🙏🏼 My goal was to stay consistent and finish feeling like I had more in the tank. Came away with a 70.3 run PB (and I had fun!!)!

Quick recovery and turn around to squeeze in one more big week of training because I’m heading to Sweden for Ironman Kalmar in three weeks 🥳

Thank you Boise for a lovely weekend! Filled my cup to see so many friends ☺️ And Brian had a good race too!

Boise, you’re cute! First time here in Idaho with ! Almost two months since my last disastrous race start. No expectations other than to have fun and put in a good hard training day tomorrow. The former is most important to me. Thanks to the wonderful companies who make sure I’m ready to rock and roll 🎸:
