19) A conundrum

I was thinking of setting this as a brainteaser tomorrow:

Your teacher has a cupboard full of shoes in her classroom and would like to run every day in January. She has a bike to travel to and from work, which can carry one pair of shoes in the panniers, whilst she wears another pair on her feet; or she could run, wearing just one pair of shoes but not carrying any. If the old trainers and new trainers are left at work, she won’t have her nice trainers to go running on Sunday; if she leaves all her shoes at home, she won’t be able to run home from work. How can she travel to and from work, wearing the correct shoes and ensuring she can go to the track on a Thursday and do her long run on Sunday? Remember, the fox will eat the chicken if left together; there is room for just 3 people in the hot air balloon; and there is only one parachute.


Please answer in full sentences and include a diagram with your explanation.

Day 19 - Run to work in stinky old running shoes
Distance: 3.85 miles
Time: 0:46:55
Pace: 12:11 min/mile
Cake rating: 3/5 (slow but beautiful morning run)

Day 19 - Cycle commute in cycling shoes
Distance: 3.92 miles
Time: 26:41
Speed: 8.8 mph (overtaken by a slug in flip flops)

Cumulative Janathising: 79.4 miles running + 75.3 miles cycling + 1.4 miles swimming


  1. Only one possible solution - buy more shoes ;)

  2. Oh no, no more shoes allowed. They all seem to end up in my cupboard at work.

  3. You may have to run/bike pulling a trailor behind you to carry all the shoes back and forth!

  4. Hmmm, you'll have to take up barefoot running!
