During the summer season, it is natural to want to diversify your training plan, especially while on a seaside holiday. Beach running can be a good addition to your usual runs, but the unstable surface places extra strain on muscles and tendons. In this article, we explain the benefits of running on sand, the risks to consider, and how to start training safely. 

Benefits of Running on Sand

Beach running can be a useful addition to your regular training plan. The soft, unstable surface requires more effort with every step, which gives this type of training several benefits.

• Building endurance. Running on sand is more challenging than running on asphalt or a treadmill: the body uses more energy to maintain the pace, while the cardiovascular system works harder.
• Strengthening the feet and calf muscles. When pushing off from the sand, the feet, calves, thighs, and glutes work more actively. These sessions can complement regular running and strength training.
• Training balance and stability. An uneven surface requires constant control of foot and body position, which engages the stabilizing muscles more actively.
• Reducing impact forces. Sand partially absorbs the impact of landing, making contact with the surface softer than when running on asphalt.

At the same time, a soft surface does not mean that the overall load is lower. Part of it shifts to the feet, calf muscles, and Achilles tendons. That is why beach running should be added to a training plan gradually.

Sand creates an unfamiliar load even for experienced runners, so the first sessions should be shorter and easier than usual. This gives the muscles and tendons time to adapt.

1. Check the route and the weather. Before you start, inspect the stretch of beach: there may be holes, stones, shells, or glass in the sand. In hot weather, train in the morning or evening, bring water, and do not run barefoot on hot sand.
2. Do a short warm-up before you start. Walk along the beach at a brisk pace, make a few circular ankle movements, calf raises, and gentle lunges. This will help prepare your feet and calves for moving on an unstable surface.
3. Shorten your first run. If you usually run 5 km, 1–1.5 km is enough for your first sand session. Focus not on your usual pace, but on how you feel and how your muscles respond.
4. Run in running shoes. If you have no experience running barefoot, shoes will protect your feet from sharp objects and help you feel more stable on an uneven surface.
5. Look for wet sand closer to the water. It sinks less under your feet, so running will feel easier. Keep the tide in mind and do not get too close to the water.
6. Consider the slope of the shoreline. Running for a long time along a sloped shoreline creates uneven loading on the legs. Change direction periodically or return along the same route.

Tip. Pay attention to how your legs feel the morning after your first session. If pain persists, gets worse, or makes it difficult to walk normally, take a break from training and consult a specialist.

Risks to Consider 

How muscle loading changes when running on asphalt and sand

Sand is softer than asphalt, but that does not mean the workout will be easy on the body. The most common issues are related to the unfamiliar load on the legs, heat, and prolonged contact with sand.

• Calf and Achilles tendon overload. As physiotherapists at Limitless Physio explain, calf muscles, Achilles tendons, and the muscles around the ankle joint work harder on unstable sand. If you increase the volume of this type of training too quickly, the body may not have enough time to adapt.
• Overheating and heat exhaustion. It can be difficult to find shade on an open beach, while the sand also becomes hot. If you feel weakness, dizziness, nausea, or a headache, stop, move to the shade, and cool down.
• A higher risk of sprains. When the feet and calves become tired, it is harder to control the landing. On uneven or loose sand, the foot may shift to the side, increasing the risk of ankle injuries.

Running on sand can diversify your training and give your muscles a new type of load. Start on firm sand, shorten the duration of your run, and increase the distance only gradually. If summer training is part of your preparation for a race, you can choose your next event in the IKS calendar and review results and personal statistics in the IKS Rank database.
