1. Picking the wrong plan or misjudging your training plan

The first mistake you can make in your half marathon training is picking a plan that is too aggressive OR too easy! This can cause you to either lose motivation or possibly get injured. You want to make sure the training plan meets you where your fitness level is NOW, not where you hope to be someday! If you’re struggling with deciding what type of plan would fit you, talk to a knowledgeable coach who can help you build a custom plan.


2. Running too fast on your easy runs

Easy runs should be just that… EASY! One of the biggest mistakes runners make is running too hard or too fast on their easy days. Taking your easy runs at an easy pace helps you to get faster in the long run, but also allows you to push yourself harder during those workout runs that might be sprinkled throughout your week.


3. Not making rest days/recovery a priority

Not allowing your body to recover can lead to burn out or injuries. Neither of which are good during a half marathon training cycle! Take rest days as seriously as you take the rest of your training. The rest days should be rest days. Your body needs the time to recover from all the hard work it is doing during this training process. Take the rest day, and ENJOY IT.


4.Not eating enough, overall! 

You can’t plan to lose weight and train properly. Eating a healthy, well balanced diet (including the occasional dessert) is essential to training. Your body needs fuel to run, just like a car needs gas to drive. If you are trying to lose weight while training for a half marathon, chances are you are going to get injured or you might completely bonk your race. FUEL your body. Before runs, during runs and after runs! Don’t forget, CARBS GIVE YOU SPARK!


5. Not testing out your race day items! Gear, clothing, shoes, fuel/hydration. NOTHING NEW ON RACE DAY!

NEVER try anything new the day of your race! You should have completed a few runs testing all the gear, clothing, sunscreen, shoes, headphones, fuel, hydration that you plan to use on race day. Keep your morning the same as your pre-long run mornings! Eat the same thing, do the same thing. It’s not worth the risk of messing up your race the day of!


BONUS MISTAKE! Neglecting strength training and only doing “cross-training”

Many runners solely focus on logging miles, disregarding the immense benefits of incorporating strength exercises as the foundation and building blocks in which those legs will handle all the miles you do during half marathon training. Strength training is NOT only an “alternative workout” to do something different from running. It is essential! When you incorporate strength training for runners into your half marathon training you’ll discover how these types of exercises can enhance your overall endurance (because your legs don’t get tired or feel heavy), prevent injuries, and take your half marathon journey to new heights.

You can teach an old dog new tricks!!!  I have never considered myself a runner and I knew I needed to be smart about it because I am no spring chicken. Spark preached getting strong and healthy to be injury free and they practice what they preach.  I am soooo glad I made the investment in me!  I finished my half marathon last weekend and couldn’t be any happier!  The program fed me all the steps I needed to essentially learn how to run long distance, build strength, nutrition help, a forum of other runners and probably most important was the 1:1 coaching.  I had no idea how to tackle training for a 1/2 marathon and this program broke all of it down, had it individualized for me and we tweaked as we went to make sure I was staying healthy and strong.  I had so many questions the week prior to my race and Coach Cat was always there for me and answering all the questions and issues I had-and believe me there were a lot!  The biggest benefit I think I got was the strength. I am strong and fit. But most important was what I gained emotionally.  I built confidence and strength I didn’t know I had, even at my age.  Honestly could not have done this without Spark Healthy Runners!

My Healthy Runner journey started after I had battled bilateral achilles pain for a few months and was frustrated how it affected my running. As soon as I talked to Duane I knew I had made the right decision. His positivity, enthusiasm and genuine care are infectious. The training plan that was tailored to me included specific exercises to rehab my injury and I was so excited that I didn’t have to stop running. It took patience to only run slow for a few weeks but I trusted the process and it got me me to where I am now: running pain free. We made adjustments to the plan throughout whenever needed having someone in your corner that is always there with guidance and support throughout the process was invaluable.

I just ran my second half marathon, both with Duane’s coaching, and PR’d by over 9 minutes! I got all choked up in the last mile when I realized that I felt strong and could still kick it up a notch.

I’m so thankful for the Healthy Runner program, community and the entire coaching team for all the support!

Wanting to run more consistently, and to increase my long run distance and total weekly mileage, I was concerned about hip pain due to hip alignment issues. This is an issue I had when I trained for my first half marathon several years ago. Having listened to the Healthy Runner podcast for the past couple years, I knew Duane Scotti could help. I signed up for the four-month strength and running training program and am extremely happy with the results.

The program Duane and Coach Whitney developed for me was exactly what I needed. It was tailored to my needs and to my target race. Coach Whitney was very helpful, and with the biweekly coaching calls, we were able to fine tune the program based off my performance and feedback.

At the end of the program, I completed a 10K trail race feeling strong and pain free.

I highly recommend Duane Scotti and the Healthy Runner training programs.
