Put in half marathon but not convinced would complete. Felt better than yesterday but it was hard work, can only suggest been overdoing it a bit as earlier 21096m's felt really good. Went out trying for 2.15 split and from start was hitting 2.14.5, it did creep up a bit on occasion but rowed harder to keep it at 2.15 last 500m sprint. Hour after finished feeling sick now.
