Very few sports supplements are actually effective...Sportlegs is one of the exceptions. An retired pro racer recommended Sportlegs to me and I was very skeptical, until I started using this. I'm a hard core cyclists and I spend enough time on the bike, that I can notice subtle changes in performance. I've been using this supplement for over a year now, and there is no question, Sportlegs makes a very noticeable improvement in my ability to push bigger gears and maintain a higher pace over the course of a ride, before my legs are fried. I hesitate to says this...but the difference for my body, is almost night and day. I can't say that you will see the same effect as I have, but give this a try and see for yourself. I'm a believer in using Sportlegs supplement.
If you're one of those cyclists who typically suffers from burning muscles on hard rides, you really want to give these a try. Take a few of these before you start your ride, then one to two an hour, and your muscles will probably feel much better at the end. These really don't help with fatigue so you're not going to be any stronger. But the muscle burn will likely be significantly diminished allowing you to push that much harder, which means in the long run you will be stronger.
I've used sports legs for years with the same results. They work! The best way to describe is after a hard pull at the front of a paceline or a full out sprint the legs seem to recover quicker. I always use them before a tough ride.
Rode a long century in the Smokies recently with over 10K of climbing and used the samples of this they were giving out, made a huge difference in recovery and legs barely sore the next day. Normally would have wiped me out. Rare to say that a product makes such a profound difference. I bought a whole bottle and take them now when I have a big ride!
It's hard to say Sportcaps boost performance, but I definitely feel less achey and depleted the day after long and/or intense workouts and races. If you ride (or do other types of exercise) in hot conditions where you sweat a lot, it's worth taking a few capsules before and after your workout or race.
Sports legs do seem to help on repeat big effort days. I use them on Sunday after a big Saturday effort. Sports doctors sell better products, which are not available OTC, are very expensive and consequently I use them sparingly. Sports Legs helps me alleviate that initial burn and will keep you going.
Pros The product seems to work well, especially on very long rides with multiple climbs when the lactic acid builds up again and again. It is not an quick fix (like a caffeine boost), but rather my legs seem to be fresher, longer. I've done my own, non-scientific testing, trying the same long rides with and without Sportlegs, and they seem to work well.
Cons Pricey. Wait until they're on sale. At 210lbs, the recommended dose is 6 capsules every couple of hours.
I use these on rides when I know I am going to suffer and they never fail me. They seem to minimize the lactic burn when I am girding out the miles. They seem to perform as advertised, but they are expensive, so I only buy them when they are on sale.
I like the smart legs much better than using the Tums I had used to keep my legs from cramping on and after rides. I find that they help in a big way. I can sleep at night without restless legs.
I was really surprised by how well these work, and the underlying rationale on the science behind it was discussed in an article in Velo News in the Spring (myths about lactic acid-lactate). I was initially thinking the effectiveness was largely a placebo effect, but after several rides (most hilly) I was impressed both by a sense of having more power-endurance and, more dramatically, far less soreness post ride.
Take 3 pre-ride as per label and try to take one per hour (when hands can safely get free!).
Overall I would at least recommend giving them a try and see what you think. A thumbs-up from me.
Delivered as promised. I am able to sustain high outputs with this product especially on the first 30 mins of the rides. My rides are flat with 15-20 mph headwinds or 1000-1500 ft climbs. 15-50 miles pending on routes.
