Longest ride before resting

Hi Got my HB3 for 10days, ride 3 times only (total ~3hrs?) I am managed to ride it continuously in 3rd gear (its not a long stretch of road, difficult to raise the speed and use 4th gear) for ~25mins, before my feet got very sore and need a rest before I can continue. I have a feeling it is due to the relatively small pedal that force me to use muscle to do the balancing. I am not a very "fit" person but I do running regularly (~50-100km per month). How far can you guys continuously riding your HB before taking a rest?

Hi there, Have in mind that it's quite normal to use more energy and take more rests during the first few weeks of halfbiking. It all comes down to getting used to the proper technique and relaxing your hands, but again, it comes with practice. Some people from the Halfbike team have managed to go up to 2 hrs without a rest and we know of other halfbikers that go for much longer.
