what the hottest shanghai marathon in history tells us about hydration you need to know

The recent Shanghai Marathon encountered the highest temperatures in its history, causing many experienced runners to almost fail. The 25°C heat and blazing sun not only affected the athletes' performance and results but also their health. Many elite runners experienced varying degrees of exhaustion after crossing the finish line, with some even needing wheelchairs to return to the rest area. The domestic women's champion, Li Zhixuan, experienced mild abdominal cramps and vomiting.

So, how should one maintain optimal condition during a marathon, especially in high-temperature situations like the Shanghai Marathon? How should hydration be managed?

Athletes generate a lot of heat during exercise, so even a comfortable 25°C for ordinary people can be detrimental to their heat dissipation, causing excessive heat accumulation and a rise in core temperature. This leads to decreased muscle contraction ability; excessive sweating and water loss can cause dehydration and electrolyte imbalance, resulting in dizziness, muscle cramps, and an inability to continue running.

In such weather, proper and scientific hydration becomes crucial. Studies show that a 2.5% dehydration can reduce running efficiency by 25%. Therefore, at marathon hydration stations, you often see a large crowd rushing to get water. The 'water' here is not just ordinary mineral water but also other types of beverages.

This is because during a marathon, the body sweats a lot, and sweat mainly consists of water, sodium, potassium, chloride, magnesium, calcium, and phosphorus. After excessive sweating, marathon participants lose a lot of salt along with water, reducing the body's regulatory ability. Simply replenishing water will only make you thirstier, failing to hydrate effectively and potentially raising body temperature.

Therefore, it's essential to replenish electrolytes and minerals along with water to compensate for the body's energy consumption. Marathon hydration stations often provide specialized sports drinks that can replenish the minerals and carbohydrates lost through sweating. These drinks help alleviate fatigue and the energy drain caused by rising body temperature. After sweating, it's suitable to drink alkaline beverages with less than 5% sugar content and containing potassium, sodium, calcium, and magnesium.

Gatorade is currently one of the most recognized sports drinks on the market. Its composition closely resembles human body fluids, making it the first choice for long-distance events like marathons. Its isotonic nature (5%-6% carbohydrates) means that its nutrients are absorbed into the bloodstream faster than plain water, juice, or soda. The sodium and potassium elements it contains can quickly and timely replenish the body, restoring electrolyte balance.

Its 6% carbohydrate content can also quickly provide energy to muscles, helping to restore athletic performance swiftly. While replenishing body functions, it also helps maintain aerobic oxidation in cells, reducing lactic acid production even during high-intensity exercise. This reduces the burden on the heart during exercise and is beneficial for energy supply during the activity and recovery afterward.

However, in high-temperature environments like the Shanghai Marathon, many people, due to heat and thirst, tend to gulp down large amounts of water at hydration stations. This can easily burden the stomach. The correct way is to take small sips, which is why the cups at hydration stations are only filled to a quarter. Stopping too frequently for hydration can also disrupt your running rhythm and affect your performance. Below is a hydration guide for a 4-hour marathon finish time for all runners to reference.

Besides sports drinks, what else can be consumed during a marathon? Freshly squeezed fruit juice, rich in nutrients and easy to digest, can also serve as a hydration beverage during a marathon. However, it is rarely provided on the course, so you might need to prepare it yourself before the race.

Additionally, some beverages should be avoided during the race, such as milk and coffee. Although they provide nutrients, they don't offer sufficient hydration. Caffeine in coffee can bind with free calcium in the body and be excreted through urine, leading to calcium depletion and osteoporosis. Also, avoid tea beverages, as the heart is already under heavy strain during intense exercise, and the caffeine in tea can further burden the heart, causing discomfort. Tea also has a diuretic effect, increasing the loss of water and electrolytes.

What other precautions should be taken during a marathon?

First, before the race, check the marathon map to understand the locations of hydration stations, which are usually marked on the official map.

1. Stay focused during the race. There are usually signs indicating the approach of hydration stations. Staying focused will help you see these signs in advance and prepare for hydration.

2. Don't stop at the first table of the hydration station. Most beginners stop here, and it can get very crowded, especially in large events. If hydration stations are on both sides of the course, choose the left side, as most people are right-handed and the right side may be more crowded.

3. Volunteers sometimes place cups or bottles on tables. If a volunteer is handing out water, taking it directly from their hand can save time.

4. When taking water from a volunteer, make eye contact so they know you are reaching for the water. Pull the cup upwards rather than sideways to avoid squeezing it and spilling the water.

5. After getting the water, don't drink it immediately. Gently squeeze the top of the cup to form a spout, allowing you to sip while running without spilling or inhaling it through your nose.

6. When you get the water, don't stop abruptly. Continue moving forward with the flow of runners. Stopping suddenly can cause collisions with those behind you. If you must stop, move to the side of the course.

7. There are usually trash bins near hydration stations. Dispose of your cup in the bin after drinking. If allowed, you can place it on the ground without obstructing others. Never throw the cup away carelessly, as it might hit other runners or spectators.
