    How Damian's hydration and fueling went...

      • Damian was leading the Spine Race until a groin injury forced him to stop after 52 hours and 35 minutes of racing. Despite the DNF, Damian was happy with the race and said “I’m thrilled with how I ran and how I felt, but obviously not happy with how things ended”
      • Before the race, Damian outlined his fueling and hydration strategy which involved consuming around 60g of carbohydrate per hour and to drink water, PH 1000 and tea over the course of the 80-85 hours he predicted he’d be racing for


      • Over the two days, Damian drank water, PH 1000, chocolate milk, energy drink mix and MANY cups of tea! The estimated total volume of fluid he drank was ~11.5L/390oz which equates to an average of ~219ml/7oz per hour over the race
      • During a race of this length, the advice is to primarily drink to thirst. As a very experienced athlete competing in his third Spine Race, Damian did this well by listening to his body and adjusting how much he was drinking depending on the conditions and section of the race. For example, he drank less overnight when the conditions were cooler, and therefore his sweat rate, and overall fluid needs were lower
      • Before the race, Damian preloaded with ~300ml/10oz of PH 1000. This is a good strategy to boost his blood plasma volume and make sure he’s starting hydrated, but we would recommend he uses the PH 1500, which contains a stronger relative sodium concentration, as this will help maximise the benefit of this preload
      • Damian got sodium on board during the race predominantly from PH 1000 and from some of the food he ate. His average sodium consumption was ~214mg/hr, which in relation to the fluid he drank meant the relative sodium concentration of his intake was ~975mg/L. Being a ‘salty sweater’, with a sweat sodium concentration of 1146mg/L, Damian did well to continue to replace a high proportion of his losses over the race
      • Damian did experience some slight twinges of cramp during the first night so decided to take on some electrolyte capsules with the aim to stave them off. Anecdotally, this can be an effective strategy to keep cramping at bay, and it seemed to work well for Damian in these circumstances as he never felt them again
      • Damian said his “hydration was always going to be compromised to an extent, especially as the race went on and availability of fluids was scarcer”. But, he stopped where he could for water and tea, was happy with his hydration strategy and didn’t feel it held him back. He also mentioned peeing plenty throughout the race, mainly for the first 24 hours, which suggests he didn’t under hydrate


    Quick Carb Calculator Recommendation


    carb 30 mins before


    carb per hour during
      • Damian prepared for the race by eating a carb-rich breakfast, this time consisting of a bowl of porridge and a banana, to top up his glycogen stores before the race started at 8:00am on the Sunday
      • For the next 3-4 days, Damian had to be self-supported; carrying his food and fluid with him until he reached each checkpoint (roughly every 8 hours) to collect more supplies, rest and regroup before hitting the trails again
      • Throughout the race, Damian ate a range of foods, including pasta, porridge, rice, a variety of energy bars, energy gels, chews, biscuits, crisps and sweets. Using such a wide range of products is important during extremely long races to avoid flavour fatigue, while continuing to get high levels of carbohydrate on board
      • Damian included real foods, such as lasagne and pizza, in his intake during the race. As he is racing at a much lower intensity than in shorter races, these are a good choice as they’re easily digested, give the body some needed sustenance over the 52-hour period and are often more satisfying to eat
      • Damian hit an average of ~38g of carbohydrate per hour. Considering the duration and intensity of this race, this is a decent carb intake, within the Quick Carb Calculator’s recommendations of 30-60g/hr, but lower than his pre-race target of 60g/hr
      • Breaking Damian’s intake down by checkpoints, we can get a more detailed picture of where he consumed more or less fuel. Damian started well, consuming over ~50g/hr between the start and checkpoint 1, and then between checkpoints 2 and 3 (end of day 1). He dropped below ~40g/hr for the rest of the race, with a large dip to ~15g/hr between hours 35 and 45
      • These fluctuations in carb consumption are to be expected during such a long race where athletes are racing through the night with little-to-no sleep, but we would recommend Damian stay within the recommended range (above 30g/hr) to avoid going for extended parts of the race without fueling
      • Damian knew that “in races of this length, energy levels are inevitably harder to control” and he did experience a few dips “when sleep deprivation kicked in”. But, overall he rated his energy levels as an 8 out of 10
      • One thing he used to combat tiredness and offset fatigue was caffeine. Damian took on a consistent dose throughout the race, using caffeinated gum and chews. Given caffeine has a half life of ~4-5 hours, during long races lasting over 24 hours, this technique to ‘drip-feed’ caffeine is a good one as it helps athletes avoid major dips and spikes in caffeine levels


      • In his third time competing in the Spine Race, Damian started off brilliantly, following his hydration and fueling strategy closely and mentioned that he was “feeling sensational” during these early stages. Unfortunately, when leading the race with ~24 hours to go, Damian had to stop due to a groin injury he picked up during the first night
      • Despite not ending the race how he would’ve liked, Damian was happy with his performance and rated his race satisfaction as 7 out of 10
      • For an event of this length, Damian’s executed a strong fueling and hydration strategy, relying on a range of real foods and energy products to fuel him well for over 52 hours; on average falling within the recommended range of carbohydrate
      • Not discouraged, Damian will be returning to the Pennine Way and has already signed up for the 2023 Spine Race. We can’t wait to see what the outcome will be when injury doesn’t hinder him!

    Athlete feedback

    Race Satisfaction
    Hydration rating
    Hydration was always going to be compromised to an extent, especially as the race went on and availability of fluid was scarcer
    Energy levels
    On something this long it's inevitably harder to control, especially when sleep deprivation kicks in. There were some small lulls on the first night and some tiredness approaching the check point, likely from lack of sleep
    Toilet stops
    I was peeing plenty in the first 24 hours. Less so after that as fluid intake inevitably lessened
    GI comfort
    No issues at all
    Twinges but not full-on cramps

    Damian's Thoughts

    Data Confidence







    There is some confidence in the quantities and brands of products consumed but the data may lack specifics (e.g. volumes specific flavours). A high number of estimations have been made and the room for error is moderate-high. There may also be the possibility that some intake has been grossly over- or under-estimated.
