Gels in hand luggage is fine as long as they are less than 100g each- they should go in one of those silly clear bags. Biscuits and sweets are fine in any quantity. I've been known to take cheese, tins of food and breakfast cereal to Switzerland even frozen meat. No questions asked.
Legs are doing fine. I've run every day, only Monday a rest day. Slight pain in my left hammy above the knee, but otherwise everything is coming back nicely.
Back to the UK due to a very ill relative- should get out for a run later though.
