Large 70 Pound Sandbag DIY


It seems that Spartan Race is making the larger sandbag, as shown above, a staple in most races.  Like I did in my previous sandbag DIY post, here, I wanted to recreate the bag as much as possible. I ended up with a 70 lbs sandbag that resembles a similar shape as the one used in the Spartan Races.


I went to my local Home Depot to pick up some of my materials for this project. The total cost only came to about $30!!! And that includes another sandbag I made, that is 55 lbs.   However, I did use the garbage bags, zip ties and gorilla tape I had left over from the previous sandbag and bucket project. So, excluding the cost of those materials it came to about $15!!! Here are the materials I used:

The Process

Compared to the previous sandbag I made, I was unable to just fit 70 lbs of sand into the woven sandbag. So, I essentially combined two to create a lengthier sandbag that could hold more sand. Here are the steps:

Step 1

First put one of the woven sandbags into the other. Next, put a garbage bag in the double woven sandbag. Following, put another garbage inside the other garbage bag. Repeat this process one time to have two separate sandbags, as shown here.

Step 2

Using the bucket and scale weigh the desired amount of sand you want in each bag. However make sure to weigh the bucket before hand and account for it when weighing the sand. The bucket used this time was 1 lb. For each sandbag I wanted 35 lbs to come to the total of 70 lbs. Since I used a smaller bucket I had to fill the bucket a couple of times.

Step 3

Once you weigh the sand and account for the weight of the bucket, dump it into the sandbag.

Step 4

Next twist the inner most garbage and make sure get as much air out. Then duct tape the top and middle of the twist. Cut off any excess bag. In the photo I put a zip tie on the bottom, but I would not recommend this because it may cut the garbage bag open.

Step 5

This is where it gets different. With the sandbags laid on its side put one sandbag in the other. Try to push it in as much as possible. Following, twist one sandbag once, to form a twist on the sandbag that is wrapped around the other. I did this because it seemed to stable the sandbag .

Step 6

Duct tape the sandbags together. Make sure to seal the sand bag all the way around.

Step 7

With one of the empty woven sandbags, slit the sides so that it can fold open.

Step 8

Using the opened woven sandbag, roll it onto the middle of the filled sandbags. I did this to provide some more support to the middle of the sandbag and where the attachment was created. Next, tape down the ends of the opened sandbag.

 Step 9

Zip tie all the corners of the constructed sandbag. Following, duct tape over the zip ties. I was unable to do this with my previous sandbags and the new 55 lbs one I made because there is too much sand in them. So there is not enough excess bag to zip tie.

Step 10

It may be a little over excessive, but duct tape the whole sandbag. The gorilla tape adds a great protective barrier. My other sandbags have had no issues so far. Plus it makes it look pretty cool!

Final Thoughts

So, there is the new and larger sandbag. For the 55 lbs sandbag you can find instructs on my previous post here. It came to 55 lbs because that was the extra sand I had left over from my 70 pounder. I think 35 lbs worked great because it left room for the two sandbags to be combined. Any more sand could hinder the ability of them to be combined.

I have used the 70 pounder already and it has worked great. It folds in the middle, but that is easy on my neck when I have it on both my shoulders. Also, I included a photo of my dog, Dwayne, next to the sandbags. He is about 40 lbs to possibly give you a better comparison haha!! I hope you find these instructions helpful!!

Sandbag and Bucket DIY


During the Spartan Championship race I had trouble with the sand bag carry and bucket brigade. We had to carry two sandbags instead of one and the bucket brigade distance was much greater than I was used to. I have to improve on these two obstacles to become a better Spartan racer. So, I sought out to replicate the obstacles the best way I could. I made my own sandbags and put together a sand filled bucket. The later was pretty much a bonus from making the sandbags.

What I purchased

You can find all the supplies at your nearest hardware store or online. I went to my local Home Depot. All products that I could find online (or something similar) are linked. Here is what I bought:

Poly-Woven Sandbag (4)

HDX Outdoor Garbage Bags (35 pack)

Zip ties (20 pack)

Gorilla Duct Tape (1 roll)

60 lbs of Sand (3)

5 Gallon Bucket and Lid (1)

Bathroom Scale

In the end, I made two sandbags, one 50 lbs and one 60 lbs and the bucket clocked in at about 75 lbs. All the supplies came to about $40. But, with 180 pounds of sand you can do a lot lighter sandbags if you desire. I didn’t use all the tape, zip ties, and garbage bags, but those are useful for other things.

The Process

When searching online I could not find a DIY sandbag that was within my budget. Until I arrived to this website. They had a very straightforward approach that had some great components. However, I didn’t follow their directions entirely but, they did inspire me to make my own sand bags and their steps helped me out a lot. So, here is my step by step process:

The Sandbag

Step 1

First, put one of the woven sandbags inside the other. Next, put a garbage bag into the double bagged sandbag and repeat that another two times. Here is a photo of what this looked like. Three garbage bags may be excessive, but I just wanted additional protection.

Step 2

Using the bucket and a scale, measure the amount of sand you want to put in the sandbag. Make sure to weigh the bucket beforehand to account for its added weight. But, a bucket usually weighs 2 lbs.

Step 3

Dump the sand you weighed into your sandbag. In the website I got inspiration from, they put the sand in the garbage bag before putting the garbage bag in the sandbag. But, I had trouble getting the filled garbage bag in the sandbag, because of the amount of sand I used.

Step 4

Working with the innermost garbage bag twist the top until tight. Make sure to get rid of most of the air on top of the bag. Next, using the duct tape, tape the top and bottom of the twist. And then cut the excess bag off. Do this for each garbage bag.

Step 5

Tie off the innermost woven sandbag with its string. Next, duct tape the top of the sandbag, zip tie over the duct tape and duct tape over the zip tie. The desired weight you want your sandbag will determine the amount of extra sandbag material you have to duct tape and zip tie. For my 60 lb sandbag I only had enough to use one zip tie, but for the 50 pounder I used two, which is the max amount you need. After finishing with the inner sandbag, do the same process for the outer sandbag.

Step 6

Duct tape over the entire constructed sandbag. This may be little much, but I felt the woven sandbag’s material was not going to last long. Also, the website I got my ideas from made handles for the sandbags. I did not follow this because I wanted it to be more difficult to carry the sandbag during training.

I have had my 50 lb sandbag for awhile now and it has held up great. At first the sandbag seems a little stiff because you have completely sealed it off and the air can’t escape. But after a couple of workouts it becomes a little more flexible depending on how much you fill it.


The Bucket

For the bucket I just used all the extra sand I had and filled it up. I had just enough to almost fill it to the brim. I figured why not make the bucket, when making the sandbags, because it is so easy.


Wrap Up

I hope this DIY project works well for you. So far it has been great for me. Now I can recreate two of the obstacles I had difficulty with at the Spartan Championship race. Even though the sandbags are different sizes, I may still use them together. The different weights will just add to the difficulty and better prepare myself for the next time I face the obstacle in a race.
