Is it possible to do 50 km distance without any previous training? I'm considering to do a 50-55 km distance on a mixed surface. Mostly asphalt and gravel, maybe even a little bit of sand. Haven't done any training or exercise, basically been sitting at home all day, everyday for years. Don't know why but suddenly had an urge to go on a journey.

My bicycle is quite old, 12 or so years, not in a great condition either but nothing is falling off so far. That wouldn't be my concern though, my concern is will my legs be able to cycle for 50 km in one go without any previous leg training. Is it advisable for me to do this? Will my legs be stiff after the first 10 km? What do you guys think?



Edit  I'm 24. Last year I tried a 30 km distance, my legs were gone after 20 and I had to step off my bicycle and walk a bit, as it seemed easier than cycling. That was my only real exercise I've done in a couple of years.

I really have all day and can take as many rests as I want. I'd say I have a solid 8 hours. Is it doable if I go on a gear that doesn't require a lot of push?
A fit person can do 50km without too much difficulty, though they'll probably be sore from the effort if they don't cycle much, just because cycling uses different muscles to, say, running.  It wouldn't be easy, but it wouldn't be too hard.

It sounds like you're not very fit. If you were determined, you could probably make it around 50km but I doubt it would be enjoyable at all.  I suggest that you start with shorter distances. Try riding 10km and see how that feels. Once you can ride 20-25km fairly comfortably, doing 50km will be a nice challenge: not easy but an achievable goal that you can look back on with pride.  Note that gravel and especially sand are more work to ride on than the equivalent distance on the road.

Since your bike's not been used for a while, you should get a bike shop to check it over. Depending on how much it was used and how it's been stored, it might need things like a new chain, new cables and new brake blocks. Possibly new tyres if they're in bad shape.

If you're going far from home, make sure you know how to repair a puncture (bring a spare inner tube so you don't have to use patches unless you puncture twice) and that you have a way of getting back if everything goes wrong.  Rather than cycling to somewhere 25km away and then coming back, consider arranging your ride as more of a circle so there's a shorter route home if things don't go well.

Make sure you bring water and snacks with you, since your first 50km will probably take at least three hours.
