Sir, – Further to the letter regarding water bottles at the Dublin Marathon (Letters, May 9th), it would be great if the organisers were inspired by this year's London Marathon. A total of 200,000 edible water "pods", made from an edible, biodegradable seaweed, were distributed to runners. Definitely something noble to consider for this island nation. – Yours, etc,
