What to expect...

You sign up for the Sundance to Spearfish marathon. Over the summer months, you spend what sometimes seems like countless miles dedicated to preparing your lungs and legs. Sacrifices are made by your family and you in an effort to support you in this endeavor. 

You show up on race day with high expectations...but... it all goes to hell and you spend the last 10k as you exit the canyon barely shuffling forward. 

Looking back, after the fact, is always 20/20 and you notice a few things that you probably could have done differently. Part of my job, as a coach, is to help my runners dial in these training considerations that may be unique to their specific event well before they show up at the starting line to be more prepared than they otherwise would have been. 

So, as you prepare for the Sundance to Spearfish Marathon, here are the top five things specific to this event you must keep in mind and put into practice to have as fun and fulfilling of an experience as possible! These may of course seem like common sense, but you know what they say about that.

(continued below)


 5) Aid Stations:  

This isn't your giant marathon with 20+ aid stations along the route or an ultra marathon with a buffet every 10 miles. 

You're going to need to bring most of your calories and hydration with you for the course. One of the biggest mistakes I see too many runners making is under-fueling their long runs and events. Simply put, the better you fuel the better you'll perform, recover, improve, ad infinitum. 

I generally suggest a couple of hundred calories hourly during long training runs and upwards of 300 hourly during long events. As race day gets closer you may move to slightly increase your hourly calorie intake and make it more specific to what you'll likely use during the race if it's different than what you use weekly during training. 

 Hydration plays a part as well and having a bladder or bottle with you to sip on as thirst dictates can be helpful. Whatever route you decide to take as far as bringing some fuel with you, practice it during training! 

4) Crowd Support:

 A bit along the same lines as the previous note, like the aid stations, there's not a ton of crowd support. 

That's not necessarily a bad thing, it's just something to keep in mind. This is a small event that starts at a fricken fire watch tower in the middle of nowhere and you may have anyone cheer for you (outside of the aid stations) until the finish line! 

Just be aware of this and that you could run the entire race solo. Having some music saved for the last half or so of the run may not be the worst idea to help you push through the final section. 

I often say that "the feeling of fatigue is fatigue" and let's be honest, sometimes running 26.2 miles feels like FOREVER and getting bored is not going to help you finish any sooner. Music is a clear performance and mood enhancer, so why not use it? 

3) Gravel:

Much of this route is on a gravel road and if you're not used to running at race pace on gravel, it'll catch you off guard. Or more appropriately, it'll catch those legs off guard! 

Performing well as a runner is very much about specificity and getting good or comfortable and the unique demands a certain event will put on you, and in this case it's running for 12 miles on a (pretty good) gravel road. If you're in the Black HIlls area getting to the course once or twice for a couple of long runs will be so invaluable, but even doing some of your regular training runs on nearby gravel roads will just help you be a bit more prepared mentally and physically for the route rather than showing up on race day not having ran on any gravel! 

2) The Last 10k:

There are two things you need to keep in mind about the final 10k; it flattens out and gets warm.

As you get to the exit of and leave the canyon it will be 3, 4, or 5 hours after you started in the early hours. The average high for marathon weekend is 70 degrees, and that's going to feel darn warm! Keep this in mind in regards to your hydration and pacing. A marathon is full of people barely moving forward during the last few miles who "had a great first half" when in fact they were not mindful of their pacing, hydration, or calories earlier on in the distance to save their stamina for the final miles, and in the case of this course the flat final 5k may feel like a climb after so much downhill. 

1) It's downhill:

If you're reading this, I'm sure if you know one thing about this event it's that it's pretty darn downhill. 

Taking this at face value, you may think "oh, I'm just going to run it faster" and while it's true that this course is likely on the quick side of things, that downhill will wreck your quads like none other. 

The reason for this is that while running on a decline your legs are lengthening but also under tension, this eccentric movement can cause much greater muscle damage than regular flat or uphill running and there are two things you can do to prepare for this.

The first is simply to make a point about doing some harder or faster running on paved downhills. During your easy runs throw a downhill 30-60 second surge in once per mile or so when you come across a nice descent. Possibly do some 800m repeats on a nice slight downhill instead of the track. You could even pick routes that will let you run longer workouts, such as tempo runs, on net downhills. All of this will come together to further prep your legs for the demands of race day. 

Second, if you don't have any great downhills or you want to double down on this, is to do an exercise that specifically eccentrically loads the quads.

Bringing it all together

Whatever your goals are, the entire point of running and training is to enjoy the process. 

Anything you can do during the 3-5 months of prep for an event and on race day itself to have as much fun and fulfillment as possible is always going to be worth it. My job as a running coach is often to simply be a facilitator of ideas and help my runners make good choices.
