In our open Facebook group we have about 3,000 members (at the time of this) and so thanks to them I have a nearly unlimited source of blog topics. A right now, a frequent question we are getting is in regards to modifying the training plan in order to fit a race in. I always chuckle at responses people give. Some are so hardcore that they feel like the schedule is the Written Word and will “scold” a person for even thinking about racing during the marathon segment! Others live for racing and would race every weekend if budget and relationships were not an issue. Their responses are the complete opposite. The truth is, well, it depends on the situation. Like anything in life there is a time and a place for everything. So let’s take a look at what our options.

My General Feelings on racing during the marathon segment

There are a lot of people who become discouraged with me when I discourage them from racing very much during a marathon training segment. For me, every race (during the marathon segment) should serve a purpose. If a person is just running the local 5k to beat a rival, but then still want to have lofty goals for the marathon, then I always have to ask them what their big picture goals are. For one, racing a 5k in the middle of a marathon segment won’t do too much for your confidence. You’re not 5k sharp, you shouldn’t have the ability to run your best 5k while training for 26 miles. If you do, then I would be concerned. If you are a new runner who’s never raced any distance very much, then you’ll see improvement, but for any seasoned runner that shouldn’t be the case.

I see two, maybe three cases, for running a race during the marathon segment. Even in these scenarios, it should be at specific times during the segment. This we will discuss later on, but for now let’s discuss the three scenarios. One is if you are trying to establish a baseline for training. Let’s say you haven’t raced anything in the last few months, and aren’t really sure what kind of marathon time you should be training for. At specific times during the segment, a race can be beneficial to get a baseline for your marathon training goals. The second scenario is performing a dress rehearsal for the marathon. The purpose here is not trying to test fitness, but rather to go through every detail that you will on your big race day. If done right, the race is not set up for the person to race all out, so they have to go in not expecting a personal best. The last scenario is if the race falls into a time when a long tempo can be replaced. Every segment runners will complain that they struggle doing the tempo’s by themselves, and there’s a race that would be a perfect substitution. While I understand the desire to have a little extra motivation to perform well on a long tempo run, I also know human tendencies. I know that more times, than not, that runners will not heed speed limits and then dig themselves a hole that takes away from other training and sets us back. I am always a lot less likely to give full on green lights for this option.

So now that we know how I feel about racing during a marathon segment, let’s discuss what to do with that training plan of yours once the rage registration is paid for.

For short races (5k or 10k)

Since the speed is done in the beginning part of the training segment, the urge is to run these short races during this block of training. Honestly, the logic here is sound, if you can race responsibility.  These are races I typically see as beginners using to establish their baselines for marathon training, rather than setting personal bests. Advanced runners may have races they run every year and they fit in fairly well with being able to do their speed workouts and substitute for shorter tempo runs.
