I ruined my knees on the first day of 2019 by doing this, thinking that it was perfectly safe to carry 48 tins and a few boxes of wine in my rucksack wearing trainers after having already done the trip once.
This year we got the coach, so we were forced to only take what we could carry, which drastically reduced the amount of nonessentials and made us pack a lot smarter, which definitely made the entry trudge a lot easier.
