Our school is 1.3 miles away, so just a little closer. Also half of it is a steep hill.
When DS was just four, we usually walked/scootered. Me with baby in sling or pram, and often pulling DS on his scooter, especially up the hill. After a little while (building up stamina) it would take us about 30 minutes up-hill. Downhill took us longer, as it was the way home from school, and we had a much more leisurely pace!
We had some really great times on our school walks. We loved the good weather and the bad (just calculate more time in, for proper clothing, and don't try to walk any distance in wellies, but get good goretex or similar walking boots and change into school shoes once arrived) and especially the evenings when it would get dark early!
It meant I walked a marathon each week, and DS at age 4 walked/scooted 20km each week.
When DS turned 5, we started to usually cycle. Yes, despite the steep hill. Me with toddler in trailer and e-bike, and up the steep bits I would often be pushing DS (which was only safe because it was a car-free road).
We invested in some very good cycling gear for rainy and cold weather!
When DS was 6-7 we often walked again, just the two of us (DD at nursery), and got the time down to about 20 minutes.
DD started school at 4.4 and from day one cycled all the way, incl. up the hill with some help/pushing.
Nowadays DS (nearly 9) flies up the hill on his bike, DD (now 5) and I follow at a more leisurely pace, but altogether we make the 1.3 miles in about 20 minutes, and I would suggest that my kids are less tired for it. We pass by DD's classmate's house at the start of our route, they are often just getting in the car, we get to school before they do.
But:
- We have a lovely route with a big part being basically through a park, and we avoid the busy road nearly completely. We see squirrels, hear woodpecks and tons of other birds, other small furry animals, and sometimes even deer. We do not encounter many moving cars at all, except for the place where we cross the busy road. When we are taking home a friend for a playdate, who is less used to walking any distance, there is a place on the way where we can stop for ice-cream and a little play.
- We do own a car and DP drives, so there is an alternative when really needed.
- There is a bus though it is terribly unreliable. Only time I've been late for pick-up is when I tried to go by bus! But if needs must, it is there.
- We soon got to know people who very kindly offer us lifts when e.g. one of the children is poorly.
I have to say, when DS was 4 it did make for long days. He left home at 8:15 and rarely got back before 4:30, despite no before/after school clubs. His friend at a different school left home at 8:50 and got home by 3:10. But one thing I never have to worry about is getting in enough exercise and fresh air! Both my children are super fit, and they have great spatial awareness.
So from my experience, it is entirely feasible, and in the end a very positive thing. But it does take some dedication, organisation, and flexibility - every now and then you might just want to pay for a taxi! (You can afford lots of taxis for the money you save by not owning/running a car!)
All that said, don't choose the nursery/school from paper! Go visit them all with an open mind, and yes, a closer school/shorter school run does have it's own advantages.
