Hi Simon – I am going to throw a spanner in here and say that afternoon XC racing can be great. If you use XC as a session then it can become your afternoon tempo or hard run. You can still fit in a morning run before. The great Bill Adcocks (read the road to Athens) used to run his 10 miler on a Saturday morning and then race the Birmingham League XC in the afternoon as a hard run. Bill was one of our true marathon legends of the 60′s etc. His book is a brilliant insight into the simplicity of running and racing hard.
However, having said this, the park runs are a huge success and there must be room for XC lges to maybe run in the morning with just the bigger National events in the afternoon allowing time for travel.
I disagree with Sarah (sorry!), Ian Byett and the ECCA do a fantastic job with a very small budget to host the National X Champs and National XC relays. These races have been the envy of many European nations over the years.
Keep training hard guys and I recommend every runner to use XC and/or Park runs to keep in tune with racing while training hard for bigger events. You can practice tactics, work hard and keep in touch with pace. Huge confidence builders also………
