Blisters, sore muscles and what seems to be a never ending training schedule are just some of the effects of preparing for a marathon. <\/span><\/p>\n Fitting in two hour runs with a busy life is just as hard as keeping your body going during them. Oh and you can say goodbye to your social life for a few months too! But, it’s all worth it to cross the finish line, get that medal around your neck and to be able to say, “I ran a marathon”. <\/span><\/p>\n<\/div>\n On Sunday, 2 October, 50,000 people will be putting on their running shoes to take part in the London Marathon. An event like no other, it’s a chance for runners to celebrate after months of training and fundraising, while being cheered on by friends, family and complete strangers. It is easy to see why it’s a challenge many runners dream of completing.<\/span><\/p>\n However, for many of those taking to the road, there’s been another obstacle to get over, one that’s not always talked about – their period. <\/span><\/p>\n Stomach cramps, insomnia and leaking are just some issues runners have to manage while on their period – issues that could affect their performance in the marathon itself.<\/span><\/p>\n Alana, a runner from Surrey, says her period has negatively impacted her training. “I’ve missed runs because I’ve suffered so badly with insomnia and a lack of energy due to my period,” she says. <\/span><\/p>\n “This then leads to being anxious. Recently I missed a 20-mile run because I got my period and I’m now worried if I’m even going to be able to do it anymore.” <\/span><\/p>\n It’s a concern of professional runners too.<\/span><\/p>\n Paula Radcliffe revealed she was suffering with period-induced cramps during the last third of her then world-record-breaking <\/span>Chicago Marathon victory in 2002.<\/span><\/a><\/p>\n During the <\/span>2022 European Championships in Munich,<\/span><\/a> high-profile British athletes Dina Asher-Smith and Eilish McColgan spoke about how their periods had negatively affected them during competitions.<\/span><\/p>\n “My menstrual cycle has always affected my training in some way,” <\/span>McColgan told BBC Sport.<\/span><\/a> “My legs usually feel very heavy and flat. Normally I’ll have bad stomach cramps, bloating and a sore lower back.” <\/span><\/p>\n McColgan is among a number of professional athletes to have called for more guidance and support on the matter.<\/span><\/p>\n “There’s no information on it at all,” says Alana. “We get sent through so much information about managing your wellbeing alongside your training, but there’s nothing to say how to manage the menstrual cycle with that. <\/span><\/p>\n “I’m likely to be on my period for marathon day, so then come the questions: how is that going to look and what can I do?”<\/span><\/p>\n Professor Kirsty Elliott-Sale, a professor of female endocrinology and exercise physiology at Manchester Metropolitan University, admits there is limited information on managing menstruation and sport.<\/span><\/p>\n “A lot of research in this area is moderate, low and very low in quality,” she says. “That is because female physiology and female endocrinology [hormones] is not taught as part of the sports science curriculum. <\/span><\/p>\n “So if you do a sports science degree, in your three years you just really hear about male physiology and male biomechanics.”<\/span><\/p>\n Another reason for the gap in research is that periods affect women differently. <\/span><\/p>\n “You’ve got world records set [by women on their period] when other women can’t get out of bed with bad cramps,” she adds.<\/span><\/p>\n Dr Juliet McGrattan, a women’s health expert and author of Run Well, wants to reassure runners they can train and perform well during their period. <\/span><\/p>\n “Science hasn’t given us all the clear recommendations that will suit everybody,” she says. “But the best way is to track your cycle, either with an app or just with a pen and paper, and see what the patterns are for you.<\/span><\/p>\n “There might be times of the month when you feel like you’re better with those intense training sessions, like interval runs or hill runs, and times when you find that your longer, endurance runs are easier. <\/span><\/p>\n “The best way really is to just see what works for you, and be flexible and adapt to try and work with your body rather fighting against it.”<\/span><\/p>\n Managing the pain with paracetamol could help, while exercise has been shown to ease symptoms for some. <\/span>A Cochrane review in 2019<\/span>
