Review: This stuff really works. Without it, my legs were on fire 🔥 after 5k race. Some fire 🔥 after 5k training and definitely total burning sensation on the legs, back, neck and arms during half marathon. I'm about 150 male so I take one pill 💊 15 to 30 minutes before training 5k run however distance and the burning 🔥 sensation of lactic acid was gone. At the 5k race events, I take 2 pills. 💊 💊 Very effective with no side effects. I stop eating 12 - 14 hrs before the race and have a handful of combination of walnuts, raisins, pumpkin seeds and almonds with a cup of mushroom coffee as hour and half before race on race day. Then small water based electrolytes pre-race drink of any choice 30 minutes before START time. I floss teeth and rinse mouth with little water as I walk to the starting line. Feeling great the whole time without burning 🔥 sensation and stiffining of muscles after during and after event. And didn't have to stop to stretch all day! I know I should stretch after the run. This is 5k experience. Going to try this out on 1/2 marathon and update my review but... this stuff really works! Why did I wait so long before trying this out? There's no taste. I take no other pills or any supplements on race day until afterwards, just supplements and light meal, preferably at end of day. There's nothing to mix. Just take with water.
Review: Worked great for my hockey game. Had legs all game!!

## Features

- GET A HEAD START. SportLegs was developed by triathletes to fast-forward training time..Taken just 30 minutes before your workout, it signals your muscles to prepare and contributes to a balanced lactic response during exercise. You get to enjoy exercise with less fatigue, “burn” and cramping, as if you’d started training weeks ago.
- EXERCISE DOESN’T HAVE TO HURT. SportLegs primes your muscles with lactate, their preferred sports fuel, in time to prepare muscles to work more efficiently and produce less lactic buildup. You hurt less without over-the-counter products. SportLegs works to make exercise become a healthy habit you actually look forward to.
- CHOSEN BY HIGH-LEVEL ATHLETES. Olympic and professional athletes have used SportLegs endurance supplement for years to train faster. It is produced in an NSF Sport-Certified facility and assessed to contain only the ingredients listed on the label.
- INEXPENSIVE TO USE. SportLegs works in just 30 minutes. You don’t have to buy extra and take it every day for weeks or even months to feel results, like many other supplements. Take 1 capsule per 50 lbs. body weight. A single 120-capsule bottle could last you an entire season.
- WHAT’S IN IT, WHAT ISN’T. SportLegs’ gentle, vegan ingredients are 87% lactate, plus 8% calcium, 4% magnesium, and 1% vitamin D for efficient absorption, in clear vegetable capsules. No sodium like electrolyte tablets or other running supplements, which can contribute to “heavy legs.” No calories either, unlike energy gels or gummies.

## Questions & Answers

**Q: Does it help with running or just cycling?**
A: I would say that it helps more for cycling, just because cyclists usually work out for longer periods of time. I am a 60 year old mountain biker and if I riding or racing for more than 2 hours, Sportslegs or something to prevent cramps is a must. I get leg cramps and cramps in my hands especially when it is hot and I am sweating. You will be surprised how quickly they work. I keep a baggy with about 10 capsules tucked under my bike shorts. When things go south you can take one every 20 minutes or so.

**Q: Will i lose my gold medal in rio if i take this?**
A: Hello!  Our guess is that if you're participating in the Rio Olympics you've already got a nutritionist telling you what to eat...but for the rest of us these are a good supplement to take.  Thanks!

**Q: What are the active ingredients beside sodium and calcium? Is this the same as an electrolyte pill?**
A: There's no sodium in SportLegs. It's not an electrolyte. SportLegs is 88% premium European natural-source lactate. Taken before exercise, SportLegs raises blood lactate, replicating the natural signal muscles obey later in exercise to curb excess lactate fuel production. Modern imaging research shows excess lactate production is the source of lactic acid. SportLegs is a clever, healthy way to help prevent lactic acid in the first place. Balanced calcium, magnesium and vitamin D are included to speed absorption.

**Q: Why is the single bottle of 120 tablets 3.84 oz and the 3 pack of 120 tables each is only 9.6 oz?  It should be 11.52 oz for 3 bottles.**
A: Poor proofreading.
