I would like to do a sponsored walk in June 2019 for a charity close to my heart. It's one of the ultra challenges and is 100k over 2 days along the Jurassic coast.
I have reasonable fitness and can do a 10 mile walk reasonably but there would be alot of work to get fit for this challenge. However I have just read the write-up on the challenge and it says you have a maximum of 36 hours to complete the 100k. So that's 2.2mph walking for the whole time. I would obviously have to go faster to have a food and toilet break and a small nap. I've done other short challenges at 3mph and that felt like a hustle. So how do people do it? Are they running? In the pictures it looks like everyone is enjoying the scenery and having a nice walk but id have to be flat out from start to finish and barely stop. Are these challenges for top althletes or am I missing something?
I really wanted a challenge to aim for in 2019 but I have a 5 and a 2 year old so my training time is limited.
