Our run testing aims to equip you with all the information you need to know in order to improve your endurance running. Whether its understanding the appropriate pace to target,nutrition requirements for training and racing or just looking to understand the limitations to improving your performance. Our Endurance Run testing removes all the guess work out of nailing that next race PB.  

How much nutrition do you need to fuel your event?

Most marathon/long distance training plans start with something like 7 miles at MP and then gradaully extending the distance out until the event usually up to ~20 miles for a marathon. While there is nothing wrong with this approach, something that is rarely considered is what happens if you are burning more carbohydrates than you're able to consume at your target marathon pace, this will go unnoticed until you get towards the peak of your marathon training or maybe not until race day itself. See below graph showing glycogen depletion from a runner who was targeting a sub 4 hour marathon. We can see from the data below that they will need ~80g/h carbohydrates to avoid htting the wall somewhere between 3:15-:3:30 and on race day if they were relying on 60g/h they would likely hit the wall at ~35km and not finish within their target time.

If in training, they were good at eating ~60g/h they would likely get to the 20 mile marker feeling good and be confident in their preperation only for it to unravel on race day leaving them frustrated and wondering where it went wrong.

Whereas, if the rate of glycogen depletion looked similar to the below graph, the runner would be capable of hitting their sub 4 hour goal provided they stuck with 60g/h during the race. Quite often the rate of glycogen depletion can be one of the reasons why two runners with similar physiologies and training, end up with different outcomes on race day.
