Is it helpful to run a race route in advance?

This is your first 5k. The first race in any event is a learning experience... when to arrive, how long it takes to sign up, where is the parking, what should you do to warm up, when are you going to use the porta-potty. I suggest that you arrive an hour before the race starts so you don't feel rushed as you do all these things for the first time.

I would start my actual warm-up routine 45 minutes or so before the race starts. That's not 45 minutes of running. It's jogging to warm up, drills, porta-potty visits, strides, and running the finish of the course to visualize the finish.

I always look at the course map before the race. Today, you can use Google street view to "run" the course and see the turns, etc.

I always run the course in reverse to about a quarter mile to the finish. I note landmarks and decide ahead of time where I will start my kick. I visual how strong and fresh I feel in that moment so I can recall that feeling when I reach that point in the race itself.

Finishes often have something unusual... a sharp turn, a confusing turn, a downhill or uphill. Running or jogging the last part of the course in your warmup can prevent surprises that cause you to miss a step or hesitate.

Also, don't stress over this. The first race of the season is always a base to work from. Approach it as a learning experience and have fun!

If you plan on leading absolutely. Every trail race I've run I never walked the course so every hill and obstacle was a surprise and it makes the course that much more exciting. After those experiences I don't think I'll ever walk a course again. But yeah I mean if you're trying to win you should get an idea of what to expect and where to go. I've been in races when I was younger wher I could've broken off, but I wasn't too confident in the signage so I stuck with the pack.

F1 drivers spend hours sim racing circuits so then know every detail.

If you can get out on an easy run and jog round the course you’ll be in a better situation to make decisions before and during the race.

I like to run the course if possible. Sometimes it'll be marked a day or two in advance, and even if not you can often follow along with a map on your phone. To me the nice things are (1) knowing where and how big the hills are, and (2) getting a feel for the last half mile or so so you can know where to kick from. Sometimes race mas will include an elevation chart but I've found sometimes the hills are significantly easier or harder than how the chart makes them seem, so it can be helpful to see them for real.

For sure if it is a trail race. For track, obviously :) it doesn't matter. Road raced, kinda a plus, but not 100% necessary.
For trail races, there can be HUGE gains by having course familiarity.

In your first race it may not matter a ton as you're probably just following everyone else and not trying to shave off every last second. You'll probably run a little faster if you are confident in where you're going but there may be some value in being surprised and just taking in the new scenery.

If you progress to longer races, you're going to want to at least know the topography (where are the uphills and downhills.)

its always beneficial to KNOW or be familiar with a course before hand. Run it, not necessarily, but know the turns on some level. Many B - level or low level races are very disorganized with volunteers who don't know what's going on , where to direct you, or on their phones

Anyone who has driven somewhere via an unfamiliar route and then taken the same return trip home knows that the mental load coming back is significantly less.

The landmarks seem closer together, the trip feels like it is quicker overall. You are able to think about other things; the directions are secondary.

Always preview the course.

It never hurts to do a little homework on a course if you're looking at setting a goal time for the distance. It can help demystify a hill if you know how long or steep it is and help you with pacing strategy if you have flat and downhill sections before or after said hill.

One piece of advice: don't try to "bank time" on a long downhill section if you have a long uphill section later on. Gravity will help you run a faster pace; pushing beyond that will add fatigue with compounding interest that will come due when you need that reserve strength the most.

Good luck with the 5k. Have fun, run hard and let us know how it goes!

given the OP is a noob, a noob should not be running the course the day of. probably not even the day before. not if they want legs when the race starts. they should warm up, of course, but we should not assume they are trained up like a college cross runner, where a couple miles for warmup might be a drop in the bucket.

as one poster noted, race day is often fairly busy. you drive to the place. park. walk to the packet pickup. get that. walk to the place to get dressed and leave your stuff. do that. walk to a spot and do some warmup. then walk to the line and wait for the race. then race, etc. it can be a little draining. so to me the last thing a noob needs is go run the course the day before. the people advising it are probably the sorts who run 5-10 miles a day.

hence why i said, do it about a week or week and a half early (or even earlier than that) or don't bother. scouting is fine but at that fitness level you want to have gas in the tank and be recovered for race day. if the race is this weekend and it's wednesday that's cutting it close, and i'd stick to my normal training. which might be similar distance but less of, run a block, wait for a light, run another, wait for it, etc. it's different running a street course in normal daytime without the cross streets blocked, tape/barriers up, etc.

if you've cut it too close you can get in your car and drive the route. it's not exactly the same as running or walking it but you can get the basic drift at lower energy expense. ok, start here. turn left there. etc.

i also agree with the other poster that a noob is most likely just following the pack and not in inch-saving mode. to me knowing the course well is more of a front of pack concern. like i did a NYRR thing and just signed up. no clue if it was a circle, up and back, or point to point. no watch, lost sense of how long i'd gone, up with the leaders to halfway, faded to top 10 or 15. yeah, that situation, you want to know, out and back, and halfway is x, because there is no one to follow and you may have to figure out your own path and pacing like it's a school meet.

Always give the course a run-through and develop your strategy.

You say, okay, I'll surge up this hill here at 1k. Then I'll recover going past this park at the top of the hill, then start pushing on the slight downhill for 2k after that.

Then steady for another 1k, but surge after that hard right turn behind some trees. That will put some distance on anyone 20 or 30 meters behind, because they don't know that trick.

Then with 1k to go there's another uphill, which you will hammer, again counter to the expectations of your opponents. With 700 to go you'll hold the effort and gradually ramp it up, Mo Farah style, and finish at a full sprint.

That way, when absolutely none of this actually happens during the race, you can blame your failure on forgetting your game plan.

I've heard that when you're running somewhere you've never been or don't know where you're going, your body naturally saves a little something in reserve 'just in case' as if it's worried about getting through some unknown obstacle to get back home. But if you know what you're getting into and where you are you can give it a full send.

if you can, always. my best tactical road 10k came from pre-running a confusing course.

there were a lot of twists and turns but i knew what was coming up and then the coup de grace on the competitors was a fuocking boardwalk - but i knew about it and how long it'd be right in the 9th km and how the sand was on it

i out kicked people at the right moments and did very well

I've also run a marathon that i didnt look at, placed in the top 10 but when i got to a key area there was no course marshal - where the fuuck do i go? i lost time there trying to figure out a non marked route.

Should have looked.

But someone else cut even worse and missed a timing mat - so I moved up a place.

something like this would only benefit you in a cross country or trail race so that you can get a feel for the hills and how fast you should be running at certain parts of the race. otherwise, i don't recommend it. if a race didn't have a bunch of hills that determine how fast you should be running, all running a race route in advance will do to you is making you overthink things.

If you get there early you may be able to walk and do your warm up on the course.

Knowing the course is important. I usually wanted the cross country runners on the course for walking and jogging even if they knew the course.

In every sport if you visualize what you are going to do correctly you will be faster. It is part of your visualization.

Maps are great. On rare occasions they are not accurate.

If I can't run the route beforehand I will drive it

For a 5K I always jogged the course just before the race. For longer races I'd run at least a few miles of the course, usually the last couple.
