The Running Channel on was forced to remove footage of giving advice on their .

Joe was offering advice and and tips specifically about training for marathons.

The Running Channel commented on the YouTube video: “In an earlier version of this video there was some discussion about , specifically around marathons, which didn’t align with advice that we would give, and wasn’t challenged enough in the discussion.

“We have since removed that short section to avoid any confusion, and in response to your feedback.”

According to the comment section, some of the advice Joe was sharing included not staying refuelled during training.

He recommended eating a banana, having a sip of water and not going to the toilet.

His comments caused a backlash with fans calling his advice “terrible” and “dangerous”.

One wrote: “I feel like no fitness professional should be saying it’s not a big deal to go outside and do consistent activity for 3 to 5 hours without fuel, water, or bathroom breaks.

Another added: “Yeah no for real this guy does NOT know what he is talking about. Research has shown MUCH MORE evidence on this than “not needing as much cause you’re not elite”.

“It’s not about being elite. It’s about biology and sports science. You do not need to be elite to be fueling a run/marathon, in fact you need to!

“Can clearly see he’s not someone who is evidence/fact based or even someone who runs long distances. Such a bad example to new runners who may not know a lot.”

A third penned: “The “good foods vs bad foods” take is oversimplified and poor advice especially for runners who actually understand fueling.

“I’ll use sugar when it’s useful in training. He has zero idea about nutrition for long distance running so do not listen to this guy.

“Feels like he’s jumped on the running bandwagon just to stay relevant. He’s said he doesn’t even enjoy it, so it just comes off as a bit of a grift to appeal to everyday runners. Why is he taking up spaces at events?”

This isn’t the first time Joe Wicks has faced backlash from fans.

In January, Joe caused an uproar after at 1 degree Celsius.

Joe shared a clip of himself taking the dip and asked fans whether they would jump in too – but many warned Joe how dangerous it was.

“Would you jump in this frozen lake? Yes or No? 1 degree C,” wrote Joe over the clip of him in the lake – during which he solely wore swimming trunks.

But many fans dubbed the stunt “very dangerous”, as one wrote in the comments: “Looks a bit dangerous”.

“No, and I do cold water swimming that’s not a good way to do it,” said another.

A third wrote: “Yes as long as I’ve been in before and acclimatised and checked for danger!

“Very important. As an ice water/cold water swimmer please don’t just do this if you’ve never done it before. Very dangerous if you don’t know the safety around ice swimming etc”.

Another claimed that it could have been a near-death experience, as they wrote: “No, having done my Aqua training an teaching regular classes I’ll always remember our tutor who told us a story about when a man jumped in the pool while the instructor nipped to the loo while no one was there.

“The man had a heart attack straight away cos his body wasn’t ready. That will always be in my mind as my duty to keep my members safe.”
