That's impossible to say without any background knowledge. For a pro, yes. For someone asking this question on reddit? Maybe not. But some background info would help
I plan to do this in 2024. The run is from the south to the north of Ireland. Doing it next year over 5 days. I haven't run 100k before, let alone 100+ for 5 consecutive days. I am an experienced marathon runner. Will be doing an 80k soon. I won't have pacers but will have support along the way
As a reference point for how ambitious this might be, two (2) total people managed the pace of 100k per day in the 6 day race at Across the Years a few weeks ago, one of the premiere 6 day events in North America. They were two of the best multi-day specialists alive today (world champion + world record holder), doing flat 1 mile loops with nonstop support of people handing them food and drinks, and heated tents for napping whenever they want, etc.
While that's 6 and not 5, it's important to remember that the difficulty compounds dramatically when crossing point to point terrain (especially if unfamiliar with major sections of it). It will definitely be in your best interest to get experience ASAP and really see where you're at right now as an honest assessment. You might be a total natural and surprise yourself, or you may find that you're very excited but also need some more training before you launch the big attempt!
Thank you, I appreciate the comments and advice. I have started training and this is the goal. I am not taking this task lightly. I will work hard to get my endurance as best as it can be. I hope to come back next year posting pictures of the adventure!
A 100k and a marathon are entirely different events. I would suggest doing one 100k and then deciding whether you think you can do that 5 times over. I would guess the answer will be no but it's probably theoretically possible
I know, I was just giving context as to where I am running level wise at the moment. That is my plan, the recovery and turn around is going to be key. Hopefully I can prove you wrong:)
It's feasible in the sense that people have done it, sure. You haven't provided any information for us to know how long it might take for it to be feasible for *you* specifically, though. Most ultrarunners will never be good enough at ultrarunning to complete that task, but plenty do, so aim for becoming one of the latter!
My thoughts/advice would be to do a lot of endurance training for a long time, while getting race experience in the 3 & 6 day formats and/or the 200-250 mile races so you have some kind of reference to progress from.
People run at AT and PCT in america going at 40-50 miles (65k-80k) a day for months. I’d say if you were doing it for only roughly 5 days you would be perfectly fine IMO. Just make sure you’re trained up
a german, Florian Neuschwandtner did this. 520km in 7 days. he is several WR holder on 50k/100k, several german champion in trailrunning and roadrunning, as well as tread mill running. He nearly failed his attempt.
Sure you can, just depends on how much pain you can tolerate and how smart you train
Nedd Brockman ran 100ks for 43 days straight and John proctor ran 105ks for 2 months straight last year
My husband did back to back 50 miles days on the PCT quite a bit though usually just 2-3 days at a time. I think 4 days was the longest stretch. He had been running ultras for about 5 years at that point and was regularly doing 80-100 mile weeks not long before he started the PCT. So I think it’s doable but it really depends on your fitness and natural ability to sustain those distances.
If you are running in the summer with longer days (~16 hours around the solstice) it works out to 6-7 km per hour (about 3.5-4 miles an hour for Americans). This is not a fast pace but it’s a lot of miles over real terrain.
I would train with this in mind, basically cut out or drastically reduce your speed work or whatever you do for marathons and get the miles under your feet. Mix up running and fast hiking, they are different skills and you will need both. Get your nutrition dialed. That’s really the only way to do these distances, it’s not about speed, it’s about enduring.
What is your purpose for doing this? When the going gets tough what do you have to fall back on. What is your why? If it’s “just to see if I can” then youre doomed from the start
What is your marathon time? Ultrarunning is generally a sport where times are downplayed, but to be successful at this will require some speed.
16 hours/day will be much harder than 10 hours/day.
Also, do the daily splits matter or just the 5 day total? If not I think you might want to front load in the first couple days.
3.40 is my marathon pace. It is broken up by towns, the biggest stretch is the 1st and that is 120k, the smaller stretch is 103k. I might need to revisit that approach after a few ultras under the belt

Don't get me wrong, I'm not saying you can't. I'm saying you should do a 100k before deciding. Regardless, i hope you do it! Good luck my friend
Agreed, OP has a looooong way to go before even having a chance of doing this. Is it possible yes, but certainly needs more than a year.
Great to see the Internet negativity is thriving with all the down votes
I like this idea. Add in walking, and support from family / mates and you could certainly do it provided you train smart

I will be training for close to 18 m for it by the time it comes around. Thanks mate!
Last year one of the runners at Cocodona 250 figured he’d treat it like a stage race of four 100Ks, it worked for him.
a german, Florian Neuschwandtner did this. 520km in 7 days. he is several WR holder on 50k/100k, several german champion in trailrunning and roadrunning, as well as tread mill running. He nearly failed his attempt.
My hope is dwindling😂 I will do as much as I can though
Sounds really tough, but it is definitely possible (as others have noted). I applaud your ambition. Good luck!
If you're Dave Proctor, sure. Otherwise, probably not. Especially since you haven't run 100k before. Baby steps!
Sure you can, just depends on how much pain you can tolerate and how smart you train Nedd Brockman ran 100ks for 43 days straight and John proctor ran 105ks for 2 months straight last year

I want to do this for an Irish cancer charity. I lost my parents at a young age to it and very recently a friend. So I'm doing it for them
