Hi, 40 yo female, been running for around a year. Currently run 3 times a week. Did first 10k at weekend in 50 mins 48 secs. The course had a couple of small hills, but was a local race so the field wasn't huge. I'm now doing the BUPA London 10,000 in 2 weeks and wondering if I can do it in under 50 mins? Put my predicted time on the form as 55 mins. Does anyone know what pen I will end up in for the start? And as it's a big field, does this mean it's quite hard to get going? Any advise appreciated, including any training tips. Am currently trying to do one speed session, one hill session and one longer run each week.
