Yep...got it. I have been using the products off and on for a bit and in different ways. It will be nothing new necessarily...just trying to dial it all in. Maybe I should wait until after race day to do the minor tweeks?
To answer your question, I will be waiting approx 50+minutes after each lap I finish. What do you suggest? I am always wanting to hear what works best for other riders even though we are not all the same...
Sounds like you have a pretty good perspective on things, with that said my suggestion would be this:
- With 50min +/- laps, your pace won't be so much an endurance pace, rather it will be multiple XC-ish intervals. Given that your pace will be quite a bit more intense than endurance there is a larger possibility that your stomach will rebel against high levels of protein.
- Given that Perpetuem is soy protein which tends to be a slower assimilating protein (in my opinion), it is a relatively high dose of protein per serving (in my opinion) and has fat content I would reduce my usage of Perpetuem during the event.
- Given that HEED is essentially just maltodextrin with some electrolytes that's not going to be enough to carry you through the entire 12hrs.
- Assuming you want to race on just liquid nutrition for the entire event (even staying on liquid while you are in the pit waiting for your partner), I would suggest mixing the two products so that you are gaining some protein advantage to help satiate hunger, trick the body into thinking you can go for a long time with the fuel it is getting and continue the continuously required repair process.
- The key is fixing the ratio so it's right for you, based on your bodyweight, level of race intensity, how accustomed your body is to processing certain fuels under certain loads (efficiency of metabolizing), etc.
- I don't know what amount of cals you have raced on previously at an XC-ish pace but it should be less than an endurance pace (as a general guideline) so take your normal endurance cal per hour and reduce it by approx 10-15% while on bike.
- As soon as you get off-bike I would suggest taking in more of the Perpetuem rather than the HEED/Perpetuem blend but get it done right away so you have a chance to assimilate it before getting to the staging tent and out on to the race course. Whatever you do, make sure you have switched to the lower protein blend at least 30mins prior to stomping on the pedals.
- My recommendation would be not to exceed your normal endurance race pace cals per hour no matter what you are consuming (straight HEED, straight Perpetuem, or a blended ratio).
- Final recommendation, err on the side of caution and under-calorie initially until you get a feel for how your body is going to process whatever you are taking during those first few laps of XC-ish pace.
I know some of this sounds complicated, it doesn't have to be, make it as simple as you want. As long as you keep your cals per hour smart and protein levels low enough everything should be ok. I'm just trying to provide some ideas for your consideration.
Disclaimer: I race on Infinit, I really like it, I stay on liquid Infinit for the duration of 24hr races and it works for me. I don't like Hammer's Perpetuem at all, I wouldn't race on Perpetuem if a free 100lb box of it fell out of the sky and landed at my feet. Hopefully Perpetuem works for you.
