Someone please contact the BBC so that Tom and his video receives the coverage he deserves!! What an incredible role model, inspiration and human-being. Oxford and his students should be so proud of him. 👍👏👏

amen to that

What a great role model! This guy needs to be on TV teaching our kids. He not only teaches math but also how to live life and be ever upbeat. Tom is our happy space on U Tube. Math was a long time ago for me but just listening to him makes me curious about how things work.

[@TomRocksMaths]

awesome thanks :)

Cool! I'm training for my first ever half marathon, now I kind of want to post a vlog about it too:D

Congratz Mr Rocks. I really enjoyed the video, especially getting to see more of the country's landscape. England is awesome. Thanks for sharing this experience

Glad you enjoyed it

"I'm never doing it again" cue to some months from now, when you may end up doing something even crazier 🙈🙈 congratulations though, well deserved! And thanks for editing this in a way that was sheer pleasure to watch 🚀

[@TomRocksMaths]

... you know me too well

[@iteerrex8166]

Awesome! I haven’t done much running but I have lots of biking. That last km looked awful, when the body doesn’t even have the energy to scream at you anymore, and you’re going purely on well power lol. Congratulations! 🏆 You know, a sponsor with a team-van full of food water first-aid, and a mattress would’ve been super.

What a great idea and what a beautiful course. You’ve inspired me to get back in shape.

[@TomRocksMaths]

good luck!!

[@lucbian]

Whilst this indeed an amazing accomplishment, I wish people were as proud and inspired by your PhD in mathematics as they are by you running 127km in 2 days.

[@arribus30]

Incredible achievement. I could feel the weight and pain in your legs in the last stretch!

just watching it now brings back the pain

Congratulations! 🏆 You’ve inspired me for the 100-mile bike ride I’m planning in a little over a week. When you got to the end of the first day I was wondering what you would do to ease the stiffness in your muscles and joints. After a ride, I rely on a good long walk to get some relief in my legs. I can’t imagine there’d be any appeal in a walk after a full day of running.

[@TomRocksMaths]

I jumped in a cold bath to try to ease my legs, and walked to the pub down the road before consuming several pints to replenish the lost salts. Also went for a short (3km) run the day after we finished just to help ease the stiffness.

[@nkhdrmv]

great effort! really inspiring and shout out to your brother and dad 🙌

[@TomRocksMaths]

thanks (from all of us) :)

definitely give it a go - start small and see how you get on, i find it a great stress-reliever

This must have been really difficult for you. How could someone handle it? A big salute to you professor.

[@TomRocksMaths]

It was very very tough. I think breaking it up into stages was really helpful as it made it seem more manageable, like just get to the next stop, refuel, and go again.

Nice! I'm training for a 50k right now. What kind of training did you do?

[@TomRocksMaths]

… erm pretty much nothing because I’m an idiot. I have a good base level of fitness - I run 10km about 2 times a week, go to the gym, play football etc. so kinda just relied on that. Terrible idea.

Why not? Running is good for the body and for the mind. Maybe not these 100+km runs though, I'll personally stick to 10 ~20km.
