Really sad and shocking news.
I never met Daz but from years browsing on this forum I was well aware of his enthusiasm, his compassion and his abilities.
I was in Keswick over the jubilee weekend BG supporting, so went up to Blackbeck Tarn to watch the Ennerdale race go by and pointed Daz out to some Hungarian tourists I met on the walk in who decided they wanted to see a fell race too.
I always assumed I'd get the chance to say hello to him somewhere.
I hope the moving tributes here are some comfort to his friends and family.
Sincere condolences.
