Much worse than the heat. Some bad route choices near the start, but pretty much held it together, then was actually running prey well and won 3 legs.
Then there was a junction I hadn't visualized right and rather than slowing down and checking it I kept going - the right way but with low confidence, then stopped early thinking I'd gone too far but actually was about 20m too short. Lost an unforgivable 30s on this leg dropping from 6th to 8th. Frustrating.
