I am looking at starting my training plan for my event next year.
It’s a Transpyrenees event of 1000km, 27000m elevation taking a maximum of 5 days.
Ive tried a custom training plan but it wont recongnise an ultra endurance event nor the 120 hours I’m expecting it to take.
Any recommendations on plan or how I can get this event to fit the training planner.
Many thanks 
Enter the event as a stage race with five separate gran fondo days.
And a quick search of the forum for ultracycling, audax, or randonneuring will turn up plenty of others with the same issue / possible solutions.
Regarding advice, I find that doing a low volume weekday plan works great for these type of events and then I supplement with MASSIVE VOLUME on the weekends. 
Thanks for the tip on how to load up the 5 day ride… all done now and a plan has been drawn up.
You can go to the calendar date and add stage race and the plan will ask you if you want it to recalculate. I did that recently but its more of a cycling holiday I’ll be doing than a race 
@mimod has the right idea with a Stage Race. This is the best way to enter in an event that spans over several days.
Once you have entered in as many of the details as you can for that event, I’d just follow the rest of the Plan Builder flow to build out a plan that works for your needs.
When we have the details of your event, we’ll plan out the training plan by using the correct training discipline alongside your training history and available time to create the right plan for you.
You don’t necessarily need to train super high hours to prepare for a long event. Most of us don’t have the time to do that anyways. What you need to do is find the volume that best works for your life in a sustainable manner and follow that plan. We’ll pick the workouts that will send the right stress signals to your body which will promote the adaptations that you need to perform well in your event.
In short, there isn’t a “best” plan for your event, but there is a “best” plan for you. 
Feed Plan Builder the details of the event and your availability and we’ll fill in the time with what we feel are the most productive workouts for you. Things will adapt along the way based on your progress too, so this is a truly custom plan! 
Thank you so much for that help.
The details are already in the plan… a 5 day 1000km 27000m event starting on the 29th June 2025. I say its 5 days, but thats the cut off, I’d love to do it quicker 
Is there anything else i need to do on the plan?
Just make sure that you’ve set up a schedule that works for you! If it looks like a solid sustainable plan, you’ll just have to follow it! 
I disagree here. Unless OP is an experienced ultra distance cyclist, regular long rides should be part of the training plan. For 3 reasons:
Bike Fit. From my own experience I can tell that a reasonable weekend ride (maybe 4-5 hours) is not going to uncover all problems with your bike fit. A 200 km might give you that insight
Nutrition Plan. For the kind of ride OP is planning on, he will need to dial in nutrition. For me that took a while to figure out.
Mental strength. On these long rides you will bonk, feel bad, and even may want to throw in the towel. You will need to learn to recognize these events within a ride, understand why they happen (nutrition, lack of sleep) and learn how to deal with them.
I’d say as OP works toward this event, long rides or even back-to-back long rides (200K on both Saturday and Sunday for example) should be part of their plan. Combine that with Threshold, Sweet Spot, Vo2Max rides throughout the week (basically whatever TR plans for you) and you should be fine.
Thanks for the insights.
I will be doing back to back 200/300 km rides soon to get into the swing of it. My biggest concern is nutrition. I am really bad at this and just go out on a 100km ride with 2 bottles of water and no further planning.
I’m by no means saying that a couple of good long rides before their taper wouldn’t be of benefit, but the bulk of their structured training for building adaptations around aerobic economy does not need to be high-volume or very long rides.
For mid-volume plans and above, we typically recommend at least one ride each week that focuses on endurance, similar to the “long run” that runners have been doing for decades. The goal of that workout is training for a sustained effort (muscular endurance, metabolic fitness, etc.).
I’ve always been an advocate for at least one longer effort before tapering for a long-distance event to make final adjustments to equipment and nutrition, but those aren’t a part of the regular training plan, so we agree on that @Duppie606.
This is going to sound heretical on a forum dedicated to TR, but nutrition, hydration, and sleep are way more important than fitness for a 4-5 day ride. Unless you’re racing for a podium spot, treat the event like you’re trying to do the most efficient bike tour possible. On bike speed / strength pales in importance to minimizing stopped time and maximizing sleep time. Tortoise mentality over rabbit mentality for the win.
Do lots of long rides to get this stuff down. No indoor training platform can prep you for this stuff and every single rider develops their own methodology for it. Listen to others, try some of their ideas, but then figure out what works best for you.
I’ve been doing audax for a long while, and have made the switch to carrying sugar-water in one of my bottles. I do 300g of sugar in a ~700ml bottle. It’s enough to keep me going for 3-4h before I stop for a refill on water (3 bottles on the bike), I use sodium citrate as the only electrolyte. Lots of threads on this forum about this approach. I’ve found it easier on the stomach than any premade mixes, my theory is the acid used in most commercial products bothers my stomach. It’s also an incredible value, easy to find almost anywhere in the world.
I guess my thoughts on following a training plan is that as my FTP increases (i hope) then my general power will increase overall.
I just need to practice eating… there’s quite a few villages and bars along the route so im hoping there will be sufficient proper food about.
Your FTP is one estimation of your aerobic fitness, which, I’d say is definitely important during a 1,000 km cycling event.
Even though those longer events aren’t about riding at, above, or sometimes even near your FTP, more aerobic fitness = more power all around. If there are going to be inclines that you’re riding up (I’ll assume so since it’s the Transpyrenees) you’re probably not going to be able to ride in your recovery or endurance zones 100% of the time unless you have MTB gearing, so building a solid engine is definitely a good piece of this puzzle!
Work on nutrition alongside your training as they go hand in hand. I’d recommend finding some sort of carbohydrate mix that works well for you and start drinking some during each ride. You’ll want to make sure that it’s something that works well for you before your big event. I can’t say enough good things about Skratch Labs. Their products focus on natural ingredients and they taste good too.
60g an hour is a good place to start and I’d work your way up to ~90g if you can. You’re going to be burning glycogen during this event, and if you can’t replace it along the way, you’ll likely hit “the wall” at some point.
Let me know if you have other questions about any of this!
Best of luck!
I did a similar ride this year, 1300km and 21000 altitude meters in 8 days…
In 2025 i will participate again.
My takeaways from this ride were:"
4-5 weeks before go to a hilly area and spend some time climbing real hills/colls.
Total volume 14-15h per week…
Built your aerobic engine but also put effort in increasing FTP…
Also make sure your core-strength is in order, maintaining a proper position on the bike for 5 full days is a challenge…
Good call on the core strength advice. I am working on that now alongside general strength training. I have already noticed an increase in leg strength on the bike 
I’ve done a few events like that, though not with the same massive amount of climbing. My plan is 2x intervals, 2x strength during the week and as much distance as I have time for at the weekend. For this year, my aim is to do at least a 200 km audax per calendar month (though my plans are already being scuppered by a storm this weekend). So nothing too complicated but, like others have said, endurance matters. And sadly for climbing body weight (in fact system weight) matters too, so I’d think about whether you can afford to lose some weight somewhere.
Losing some weight somewhere is something on my mind. As I’m doing strength training now I don’t think I’ll physically lose much weight. Initially looking at the bike packing equipment (starting totally from scratch) I was looking at the biggest saddle pack, biggest bar pack etc to carry loads of stuff… but I think thats where I need to be realistic and can cut down.
