Recently, there’s been a lot of online criticism aimed at running influencers who get injured, with much of the blame being placed on the Runna app. Many influencers are sponsored by Runna, so you often see them posting workouts, racing frequently, and unfortunately, sometimes dealing with injuries.
But here’s the thing: running injuries are rarely caused by a single factor and it’s not fair to blame an app.
There are countless reasons runners get injured: increasing weekly mileage too quickly, skipping strength training, inadequate fueling, poor recovery, life stress, or running every run too hard. Placing all the responsibility on an AI training app oversimplifies a much more complex issue.
I know this firsthand. During my first marathon training block, I developed IT band syndrome, and I wasn’t using any AI running app at all. I got injured because I ramped up my mileage too fast, didn’t strength train and ran nearly every run at a hard pace.
Ironically, since I started using Runna, I’ve been injury-free! My past year of training with the app has been overwhelmingly positive. That said, I’m not a beginner runner. I’ve built enough experience to recognize when I need to adjust a workout or back off if something feels off.
There are plenty of running apps out there promising faster times, smarter training, and fewer injuries. I’ve tried Pinterest plans, generic schedules, and plenty of trial and error, and I’ve learned that no single plan works for every runner. Runna may not be for everyone, but I don’t think it should be dismissed solely because of negative internet chatter.
What Is the Runna App?
Runna is an AI-powered running training app that builds a personalized plan based on your goals, experience, and timeline. You can use it to:
-
Train for races like a 5K, 10K, half marathon, or marathon
-
Maintain fitness between races
-
Prepare for non-traditional events like Hyrox
Each plan includes a mix of:
-
Easy runs
-
Tempo runs
-
Speed workouts
-
Race-pace runs
Everything is tailored to your current fitness level and race date, which makes the training feel intentional rather than random.
My First Experience With Runna: A 10K PR
The first time I used Runna was while training for a local 10K in April 2025 and I PR’d!
I held a pace under 8 minutes per mile for all 6.2 miles, something I genuinely didn’t think was possible for me. That result alone got my attention.
What stood out most was the structure. The variety of workouts made training feel purposeful instead of repetitive. I wasn’t just logging miles, I understood why I was doing each run and learning about the benefits of different running workouts.
Using Runna Beyond Traditional Races
One thing I didn’t expect was how versatile the app could be. I later used Runna to help my cousin train for a Hyrox race. Yes, Runna isn’t just for road racing!
The fact that it could adapt to fitness-based events made it clear this wasn’t a one-size-fits-all program.
Training for the Kiawah Marathon With Runna
Runna really proved itself during my Kiawah Marathon training block, especially with the speed workouts.
In past marathon cycles, if I had a seven-mile weekday run on the schedule, I dreaded it. After a long workday, seven easy miles felt mentally exhausting.
But a seven-mile speed workout?
The time flew by!
Intervals, pace changes, and built-in structure made weekday runs engaging instead of monotonous. Suddenly, those runs felt manageable and even motivating.
Speed Workouts: Scary at First, Empowering Later
I’ll be honest: the target paces for some speed workouts initially felt intimidating. Sometimes they felt impossible. But more often than not, I surprised myself by running faster than I thought I could.
And let’s be real, who doesn’t love built-in walking recoveries?! Those recovery intervals made hard efforts feel doable and kept me mentally engaged throughout the run.
If you struggle to hit assigned paces, Runna automatically adjusts future workouts. You can also switch to RPE (Rate of Perceived Effort) instead of strict pace targets, which was a lifesaver for me. During August marathon training in 90+ degrees with 98% humidity with a 12-mile progression run, target pace simply wasn’t realistic. RPE made those workouts achievable.
Why Proper App Use Matters (and How Injuries Happen)
I think a major reason some runners get injured is not using Runna’s features honestly or correctly.
The app allows you to:
-
Choose training volume (gentle, steady, or progressive high volume)
-
Adjust workout difficulty (comfortable, balanced, or challenging)
-
Input your current weekly mileage and longest recent run
-
Log illness so Runna can adjust paces
-
Skip, move, or shorten workouts when needed
It’s crucial to be honest when entering your current fitness level. If you tell Runna you’re running 30 miles a week when you’re not, or input a faster race time than you can realistically run, you’re setting yourself up for injury. Increasing weekly mileage too quickly is one of the most common causes of running injuries.
Runna is adaptive, but accountability still matters.
Strength and Mobility: Built In (and Actually Done)
Runna also includes strength training and mobility workouts that can be added directly into your plan. These are essential for injury prevention, especially during marathon training.
Having them scheduled made me far more likely to actually do them. No guessing, no skipping, no “I’ll do it later.”
That said, I’ll be honest. The strength workouts did feel repetitive week to week. I often supplemented them with runner-specific exercises I learned from physical therapy, especially glute-focused work (my biggest weakness). Runna can’t yet customize workouts for specific muscle imbalances, so your own knowledge still plays an important role.
Why Runna Makes Sense for My Life
Would a real-life running coach be more personalized? Absolutely!
Would I love one? Also yes!
But coaching is expensive, and that’s not something I can budget for right now.
For about $20 a month, Runna is affordable, accessible, and effective for my current season of life. Another huge bonus is that it syncs directly to my watch. My watch alerts me when:
-
An interval is complete
-
I’m running too fast
-
I’m running too slow
I don’t have to constantly check my pace, I can run by feel and let the beeps guide me.
Tracking Progress and Staying Motivated
One of my favorite features is how Runna tracks PRs across multiple distances. Seeing tangible progress throughout a training block is incredibly motivating, especially on days when confidence feels low.
Some runs are hard.
But they pay off!
Final Thoughts
Runna isn’t magic. You still have to show up, do the work, and listen to your body. But if you’re looking for a structured, adaptive, and affordable training plan that keeps running interesting, Runna is absolutely worth trying.
It helped me PR a 10K.
It helped me train smarter.
And it played a big role in my sub-4-hour marathon at Kiawah.
Sometimes, the hard workouts are the ones that matter most.

Just remember be honest when setting up your plan so you can have success and not injury!
